Your model.
Your cuts.
Your way.
Split STL and 3MF models along flat or curved seams, add alignment keys or magnet sockets, and export print-ready parts — all in your browser. Your model is never uploaded.
ModelSplitter Pro launches on Kickstarter at the end of November 2026. Everything is free and unlocked in the public beta until then. Try it on your own model first.
WINa lifetime Pro licence — join the launch list
Everyone on the list when the Kickstarter goes live is entered. Three names are drawn on launch day and each wins Founding Backer Access — the lifetime Pro licence. How the draw works.
Follow on Kickstarter — notify me on launchFollowing is what tells you the moment it goes live — and the Early Bird price is for the first 50.

A focused toolkit for the awkward cuts
Follow a difficult seam on a miniature, divide a large prop into printable sections, or prepare a batch of parts for a studio — without a detour through a full 3D modelling package.
Split with control
Flat and curved seams, line, band, rope and painted-region cuts, and automatic multi-plane cuts for models larger than your printer.
Make it fit together
Fixed pins, loose alignment keys and magnet sockets with adjustable clearance. Joint numbering keeps larger assemblies straight.
Refine and export
Repair, sculpt, engrave and create inlays. Export named parts in one ZIP or a single 3MF, with an assembly manifest and a PDF guide.
One payment. No subscription.
The beta has every tool unlocked. At version 1.0, ModelSplitter divides into a Free edition and Pro. Kickstarter backers get Founding Backer Access: every Pro feature, current and future, for as long as ModelSplitter operates — and they keep every Pro tool when the beta divides.
