From Miniature to Massive
Split and key any 3D model — exactly where you want
Draw natural seams, make straight or automatic cuts, add matching keys and export printable parts — privately in your browser. Paint a region or draw a seam, cut the model along it, and it fits the pegs and sockets that bring the parts back together in one position.

Free public beta — all current tools unlocked for testing. ModelSplitter runs locally in your browser, so your model is never uploaded. During the beta it does send anonymous counts — which tools get used, how long a cut took, when one fails — so we can see what to fix. Never your model, its name, or anything you type — the one exception is the feedback box, which sends exactly what you wrote in it, and only when you press Send. Features and Free/Pro availability may change before version 1. Kickstarter backers get every Pro feature, current and future, for as long as ModelSplitter operates. Best on a desktop or laptop: it wants a mouse and room to see the model.
