Kickstarter tells you the moment it goes live, so you can be one of the first 50.
Nothing is charged until the campaign ends, and only if it is funded.

The list gets the launch announcement and development updates. Joining doesn't reserve an early-bird place. Everyone on the list is also entered in the launch draw for one of three Pro licences. How the draw works. Unsubscribe any time.
It isn't only for models too big for your printer
Miniatures and limbs
Take off an arm, a head or a weapon along a curved seam that follows the model, so the join hides where it should.
Large models and props
Split a helmet or a statue into sections that fit your printer, with alignment keys so the parts go back together straight.
Inlays
Pop out an eye, a gem or a badge as its own part, and print it in another colour. It presses back into place.
Pop out any detail and print it in another colour
Draw around an eye, a gem or a badge on your model and choose a depth. ModelSplitter cuts the pocket and the matching plug, and they press back together after printing.
Multicolour on a single-colour printer, with no CAD and no booleans. The eyes and pupils on this mosquito were cut that way and printed in black and white on a single-colour Bambu Lab printer.
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.
Try it now, on your own model
Drop in an STL or 3MF, make a cut, add pins and export the parts. No account, no payment, and your model isn't uploaded. Every tool is unlocked until the Kickstarter.

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.

Every paid tier includes priority email support for the first year after version 1.0. Not included: any usage-based service (such as a paid AI feature); none is planned for launch.
Built by one maker
I'm Nick. I build ModelSplitter myself, and I test the tools by printing with them: the mosquito above came off my own printer. Every message from the feedback box and every email to hello@modelsplitter.com comes straight to me, and what testers ask for is what gets built next.
