1.0.52 2 Oct 2026 Latest

The big one. Three new tools in Snappy Pro: the Part Splitter cuts a model that is too big for your printer into pieces that fit, with connectors; the Shaper makes parts to exact sizes; and the Aligner lines parts up while you design, puts them on the plate, and fits split pieces back together.

  • New Part Splitter. Pick your printer and Snappy shows its build volume around the model. Auto-Cut places the fewest seams that make every piece fit, or add and drag seams yourself; anything still too big for the plate shows in red as you go. The preview shows the real pieces with their connectors, then Split and Lay Out on Plates. Snappy Pro.
  • New Connectors. Pins, tapered pins, hex pins, dovetails, T-slots or a shape of your own, sized to the wall they sit in, kept off thin walls and cut with Snappy’s clearance engine. One size for the whole model. Where a joint’s wall is too thin for that, Keep Off Walls steps down for that joint alone (as far as the thinnest wall your printer prints, a preference you set once from the Connector Test), the pins there show amber, and one line sums it up: how many at full wall, how many thinner, and which joints got none and need glue. Accept thin walls makes every amber pin grey in one click; Show bare joints selects the pieces to glue. Print them in the pieces or separately. Snappy Pro.
  • New Print a Connector Test. One small plate, sent straight to your slicer: a row of sockets in walls from 0.6 to 1.5 mm and a row at clearances from 0.10 to 0.30 mm, for the connector and size you are using, with two pins to try. A dovetail or T-slot gets its own test: a groove in each block and two rails to slide along them. Snappy Pro.
  • New Shaper. Boxes, cylinders, tubes, cones and spheres made to the millimetre and edited by typing numbers. Use a shape as a Base, a cutter or your own connector. Split one and its pieces stay Shaper parts you can resize, holes intact. Snappy Pro.
  • New Aligner. Line parts up while you design, in two clicks: Flush, Same Axis, Centre On and Match work on any parts, not only ones Snappy has split. The click tools show a ghost preview of the part exactly where the click would put it, before you commit, and the buttons leave a short fading trail from where a part was. For printing: Lay on Face, Lay Flat, Auto Place, Drop to Plate, Centre on Bed and Spread on Bed. Auto Align puts a whole split back together, and also works on downloaded multi-part models. Snappy Pro.
  • New Snappy Free gets Lay on Face, Drop to Plate and your printer’s bed drawn under the part.
  • New Fifty-three more printers in the list, Snapmaker U1 among them. Saved files keep the printer they chose. Both editions.
  • New Click a coloured part in the preview to see what it is: a small window says what is wrong in one line and puts the fix on a button (Accept thin walls, Print a Connector Test, Smaller connectors, Try dovetails, Auto-Cut). Snappy Pro.
  • Change The Cutter and the Splitter work on each other’s parts: a Base with a cutter can be split and keeps its cut set if you undo the cut, and a split piece can take a cutter of its own. Snappy Pro.
  • Change Send to Slicer writes one 3MF with every part in place. STL is still a choice. Snappy Pro.
  • Change Less text on the panels. How-to text sits behind a small i: rest the mouse on it to read. Warnings only show when there is something to do. Snappy Pro.
  • Change Reset Snappy clears everything either edition made, including the printer outline. Both editions.
  • Fixed Blender could crash when you joined (Ctrl+J) something into a model that used to be a cutter, after Reset Snappy or removing the cutter. Both editions.
  • Fixed A Shaper shape used as a cutter keeps driving its cut while the cutter is hidden. Snappy Pro.
  • Fixed A cutter mirrored with a negative scale cut its hole in the wrong place, and with the cutter selected the cut switched off and stayed off. Snappy Pro.
  • Fixed Delete every piece of a split by hand and the model comes back with its seams, instead of a seam left standing over a model you could not see. Snappy Pro.
  • Fixed A model turned or laid flat straight after adding a seam, or just after opening the file, kept its seam with it. Snappy Pro.
  • Fixed An Edit Mode change to any part of the model under a live preview is noticed, whichever vertices moved. Snappy Pro.
  • Fixed Redo (Ctrl+Shift+Z) of a duplicate or a join no longer leaves the preview one step behind. Snappy Pro.
  • Fixed Ctrl+Z on a seam you moved under a live preview goes back one move, not two, and redo brings the whole move back. Snappy Pro.
  • Fixed Shape of your own with no shape picked no longer prints an error in the console. Snappy Pro.
  • Fixed Send Selected Sets sent every split part in the file, whatever was selected. It now sends the sets you select: every piece and joiner pin cut from the model you picked a piece of, plus anything else you have selected. Snappy Pro.
  • Fixed Lay Out on the Plate left some pieces floating above the plate, and stood some on a curve. Every piece now rests on the plate on one of its big flat faces, never on its pegs. Snappy Pro.
  • Change The Aligner’s bed and the Splitter’s printer outline can both show at once for different parts, and each part uses its own. Snappy Pro.
  • Fixed A blue part (a bit of a cut that prints with the piece it touches) printed on its own after Split, even though the preview showed it joining its piece. It now joins as shown, and the preview draws its pin and hole the way they print. Snappy Pro.
  • Fixed A pin could show for a moment after Auto-Cut and then vanish, leaving a joint one pin short: it sat on a loose bit that goes to the piece across another seam. That pin still holds the loose bit, and the joint now gets a pin of its own. Snappy Pro.
  • Fixed A face that came out with fewer pins than asked stayed that way, even where a pin fits. A rebuild now adds the missing pins; pins already there, including ones you dragged, do not move, and a face you accepted with Fine, leave them is left alone. Snappy Pro.
  • Fixed Two pins on a long face sat side by side at one end instead of one at each end. Snappy now picks a pin size (or, down to your thinnest wall, a closer keep-off-the-walls) that puts them at the ends, and a narrow face puts its pins at the ends rather than a third of the way in. Expect smaller pins on such faces, and some amber ones where they sit closer to the wall. Snappy Pro.
  • Fixed Dovetails and T-slots on a hollow or thin-walled model run along the wall instead of straight through it. A joint with room only for a stub gets no rail, and the panel says how many joints to glue - and when a third or more of the joints are like that, that rails do not suit the model and to switch to pins. Snappy Pro.
  • Fixed Choosing a dovetail or T-slot, then pins again, set Connectors per Face back on the active seam only; the other seams kept the rail's one per face, while the field said two. Both switches now reach every seam of the model. Snappy Pro.
  • Fixed The printer outline stands on the plate (Z = 0) instead of on the model’s lowest point, so a part above or below the plate looks that way and Drop to Plate visibly lands it; the button also says how far the part moved. Snappy Pro.
  • Fixed A joint that holds fewer pins than Connectors per Face shows it on the model: its pins are amber, and clicking one says why (the face is in separate bits and one is too thin for a pin, the wall thins away from the seam, or there is too little material behind it). Fine, leave them turns them grey. Snappy Pro.
  • Fixed A dovetail or T-slot joint that got no rail wears a red ball on the model. Click it to see why, with Switch to pins on the pop-up. Snappy Pro.
  • Fixed Split a model, then use the last piece left as a cutter, and the model still counts as split: Split stays greyed, and Undo the Cut takes that cut set away with the piece. Snappy Pro.

1.0.51 8 Aug 2026

A safety fix for the updater: Snappy no longer closes Blender on a project you have never saved.

  • Fixed Installing a Snappy update could close Blender while your project had never been saved, writing it to a temporary folder you would not think to look in. Snappy now asks you to save your project first, and the update prompt says plainly that Blender will close and reopen. Both editions.

1.0.50 8 Aug 2026

A cut could remove your whole part. Snappy now checks the result of every cut and keeps your model on screen.

  • Fixed On some models the base disappeared after a cut, even though the model itself was fine. Snappy now checks every cut, and if one would wipe out the whole base it retries with safer settings. If it still cannot cut cleanly it leaves your part on screen, turns the cut off, and tells you why. Both editions.
  • Fixed The Report an Issue window’s two buttons — Report an Issue and Give Feedback — were blank, so there was no way to tell which was which. Snappy Pro.

1.0.49 30 Jul 2026

Two fixes: a cutter whose origin you changed no longer cuts in the wrong place, and the Troubleshooting panel stops wiping its result every time you click something else.

  • Fixed Changing a cutter’s origin (Object > Set Origin > Origin to Geometry) while it was connected to a base left the cut in the old position, offset by exactly the distance the origin moved. Moving the cutter afterwards could push the cut off the part altogether. Both editions.
  • Fixed The Troubleshooting panel reset its result every time you selected a different object or cut set. The last check now stays on screen with a quiet note saying which part it belongs to, and only the repair buttons switch off until you check the current selection again.

1.0.48 29 Jul 2026

Mesh repair got a serious going-over: it no longer damages the model it is repairing, no longer claims success it has not earned, and Force Fix now hands back far lighter meshes.

  • New Check a part on its own, before it is in a cut set (Pro). Select a mesh and press Check Selected Object. Cleaning geometry first is what stops Booleans failing.
  • Change Fix results are much easier to read: a plain verdict, the part it applies to, and a tick-list of what actually changed.
  • Change Each repair button greys out once it has been run on a part, so it is clear the operation has completed.
  • Fixed Repair could report "watertight, 0 issues left" while leaving a stray spike attached and deleting part of the real surface. It now removes the stray piece and leaves your shape alone.
  • Fixed Repair can no longer leave a model worse than it found it. Every step is measured and undone if it did not help.
  • Fixed Repair could claim success while the panel still showed problems. The message and the panel now come from the same check.
  • Fixed Force Fix did nothing on self-intersecting parts, so pressing it just repeated the same message. It now rebuilds them properly.
  • Fixed Force Fix produced needlessly heavy meshes - a simple block came back with 123,000 faces. Flat areas are now merged back down (that block is now 220 faces), which stops the viewport lagging.
  • Fixed Force Fix rebuilt parts made of several separate solids even though they were already fine.
  • Fixed Repairing the low-resolution preview stand-in raised a Python error. Diagnose and Fix now always act on the real object.
  • Fixed The Troubleshooting panel kept showing the previous result after you picked a different Base or Cutter, and the buttons still acted on the old part. It now asks you to run Diagnose again. Both editions.

1.0.47 28 Jul 2026

A lead-in chamfer so parts go in easier, a cutter list that stops the panel growing forever, and in-app mesh repair for Pro.

  • New Ease-In Entry (Pro) bevels the mouth of a hole so the mating part goes in easier instead of catching on the top layer. Works on any cutter shape; best on a flat surface with a fairly simple shape.
  • New In-app mesh repair (Pro). Diagnose tells you which part is the problem, then Fix or Force Fix repairs it without leaving Blender. Still early - please use Report Issue if it does not do what you expect.
  • New Splitting a piece off a cutter now hands it back as a plain object instead of a half-cutter.
  • Change Cutting Sets is now a fixed-height scrollable list, so the panel stays the same size whether you have two cutters or twenty. Click a row to select that cutter in the viewport.
  • Change Each cutter row now has its own buttons for visibility, colour and export. Export is a real button rather than a tiny checkbox.
  • Change Free: Scene Setup collapses to a single "Units ready" line once prepared, the same as Pro.
  • Change Free: each part that needs work now has a one-click Repair with Formware button for free online repair. In-app Fix / Force Fix are Pro only.
  • Change The report button is now called Report Issue in both Free and Pro.
  • Fixed Blender could crash when you duplicated a base that had a cutter and then pressed Ctrl+Z.
  • Fixed Blender could crash when undoing after an in-app repair.
  • Fixed Cutters made of several separate parts were wrongly flagged as needing repair.
  • Fixed Repair could delete intentional separate parts of a cutter. Only tiny stray fragments are removed now.
  • Fixed The clearance-test Start, End and Step fields were cut off at larger interface scales.

1.0.46 26 Jul 2026

Sorry for the run of updates today — this one clears an update-prompt loop that slipped into the earlier builds. Thanks for bearing with me.

  • Fixed The “update available” prompt kept showing even after you had updated.
  • Change Cutters with stray or open edges can be added now — only genuinely unsafe non-manifold geometry is still blocked.

1.0.45 26 Jul 2026

  • Fixed Plain hole cutters now cut an exact-size cavity with no gap, as intended — they were still opening the normal fit clearance. (Pro)
  • Change Setting a cutter to Plain hole now switches its Export to Exclude automatically, since a plain hole has no printed part. (Pro)
  • Change Fitted part / Plain hole are now toggle buttons — click the highlighted one again to clear it back to a normal fitted cut.
  • Change The clearance test now saves all three files into one “Snappy Clearance Test” folder, so the parts no longer scatter loose in your downloads.
  • Change Shorter, clearer tooltips throughout both editions.
  • New I’m building an in-app mesh fixer to repair broken meshes right inside Snappy before cutting. Still in prototyping — coming in a future update.

1.0.43 25 Jul 2026

  • New Warnings now appear in the middle of the viewport instead of the status bar, so you cannot miss them.
  • Fixed Selecting a fresh object now clears the Base and Cutter fields, so you can see at a glance that nothing is assigned yet.
  • Fixed The panel updates on the first click instead of needing a second.
  • Fixed Cutters stay connected to their Base. Selecting a Cutter and then clicking elsewhere no longer leaves it detached.
  • Fixed An object can no longer be used as both a Base and a Cutter, which could chain parts together so everything moved as one.
  • Fixed Duplicating a Base now gives you a normal object, instead of a copy that could not be used as a Cutter.
  • Fixed Cuts no longer appear in scenes they do not belong to.
  • Fixed The Cutter no longer keeps an empty material slot after a reset.
  • Change The clearance test and its fit guide each print as one solid piece.
  • Change The solver button is greyed out on a Cutter set to Union or Intersect.

1.0.42 25 Jul 2026

  • Fixed Reset Cut in Snappy Free now really resets: the cut is removed, the orange outline disappears, and the Cutter is unlocked so you can move it and cut again. The Cutter is handed back exactly as you had it.
  • Fixed Editing a Cutter in Edit Mode could crash Blender on undo. (Pro)
  • Fixed Cutters no longer flicker or stall while you edit them. (Pro)
  • Fixed A Reset Cut Set error that could stop a cut preview rebuilding. (Pro)
  • Change The sliding clearance test now uses straight parallel rails instead of a dovetail. Straight faces transfer far better to lids, drawers and guide rails than an angle-specific dovetail.
  • New Every clearance-test export now includes a clearly named FIT GUIDE file for reference, and Free and Pro export the same test.
  • Change Selecting a Cutter now lets you snap it to its own Base. (Pro)
  • Change The clearance-test accuracy reminder is now a popup shown when you create the test, so it is read rather than scrolled past.

1.0.41 24 Jul 2026

  • Fixed Snappy Pro 1.0.40 could not be installed or activated — Blender reported “Add-on not loaded… cannot import name ‘hot_reload’”. Pro installs normally again. If you hit this, just install 1.0.41 over the top: no need to uninstall first, and your activation key is unaffected. Snappy Free was never affected.

1.0.40 24 Jul 2026

  • New Automatic update alerts — Snappy now checks for a new version when Blender starts and shows a popup plus a banner at the top of the panel the moment an update is available. You can still check any time from the Help section.

1.0.39 24 Jul 2026

  • FixedDeleting a cutter now removes every trace — no leftover wireframe. (Free + Pro)
  • NewCalibration test redesigned: clearer part labels and a dovetail slide test, and every fit (round, block, dovetail) prints the exact labelled gap.
  • ChangeTidier cutter controls; the Exact solver’s self-intersection and hole-tolerant options now sit right under the solver. (Pro)
  • ChangeNavigating between cutters and cut sets now frames the view cleanly.

1.0.38 23 Jul 2026

  • FixedScaling a base with its cutter attached now rebuilds the clearance automatically — no need to press Prepare Scene Units again. (Pro)

1.0.37 23 Jul 2026

  • FixedScaling a base and its cutter together no longer breaks the cut — the clearance rebuilds at the new size. (Pro)
  • NewSend Selected Sets — select the bases you want and export just those cutting sets. (Pro)
  • ChangeUnion and Intersect moved into Selected Cutter Options as advanced Boolean options; Difference stays the default fitting cut. (Pro)
  • FixedCalibration test pins no longer overlap the base.

1.0.36 23 Jul 2026

  • NewCustom clearance is now a button beside the fit presets, so entering your own gap is as easy to find as a preset.
  • ChangeThe calibration test prints as one piece — the round, slot and slide channels now share a single base.
  • ChangeThe per-cutter Export toggle reads “Export Off” when it is disabled. (Pro)

1.0.35 23 Jul 2026

  • FixedIntersect mode now respects clearance — parts were coming out oversized. (Pro)
  • FixedRare crash on first install when Free and Pro were both enabled.
  • FixedTutorial and Manual Download buttons not opening on some systems.
  • ChangeTutorial button now opens the Quick Start guide.

1.0.34 22 Jul 2026

  • NewFive fit presets: Press, Tight, Normal, Loose and Free Running.
  • ChangeFilament choice now adds clearance instead of scaling it, so the fit names mean the same thing on every material.
  • FixedCalibration test coupon now prints the exact gaps shown on its labels.

1.0.33 22 Jul 2026

  • ChangeClearance now means the real gap between the two parts — set 0.1 mm, get a 0.1 mm gap. Existing projects become tighter; reprint a test piece before a full print.
  • NewPer-cutter clearance in Pro — every cutter can carry its own gap.
  • FixedProtected faces receiving only half the requested clearance.
  • FixedCutter splaying when two protected faces meet at a shallow angle.
  • ChangeCut outline follows the cutter's visibility (shown in Visible and Wireframe, hidden in Hidden).
  • ChangeApplying a cut is now clearly the final step — it bakes the cut and removes that cutter, its outline and its printable part.
