“I have been looking for something like this for years, it is something i have to get used to, and i would like some alterations, but what i tried so far works and takes out the manual hassle.”

Compare Snappy Free & Pro

Start with the essential fitting workflow for free, or unlock Pro for the Part Splitter, the Shaper, the Aligner, multiple cutters and organised exports.

✦

Built for real fitting workflows

Create repeatable, printable clearances while keeping the original shapes available.

◫

Split to fit your printer

Auto-Cut places the fewest seams that make every piece fit your printer, adds connectors sized to each wall, and lays the pieces out on plates.

△

Parts to the millimetre

Boxes, cylinders, tubes, cones and spheres made to exact sizes. Type a new number and the shape rebuilds, even after it has been split.

⊕

Line up in two clicks

Flush, Same Axis, Centre On and Match show a ghost of where the part will land before you click. Auto Align puts a split back together.

◎

Physical millimetres

Clearance tests and exported geometry share the same dimensional pipeline.

◇

Non-destructive previews

Position and review fitted parts before applying the final cut.

⚙

Boolean troubleshooting

Switch solvers, diagnose geometry and follow guided repair steps.

▦

Cutting sets

Keep bases and their cutters organised and independently configurable.

↔

Protected stop faces

Keep intentional flush stops on lids, rails and connectors.
