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 sends anonymous counts, with no cookie or ID, so we can see what to fix. Never your model, its name, or anything you type — with two exceptions, each only when you press its button: the feedback box sends exactly what you wrote in it, and the launch-list form sends your email address to MailerLite. Nothing from another company loads unless you ask to join the Pro launch list, which uses MailerLite's sign-up form. 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.
Exactly what is counted
Which tools and cut methods get used, the rough size of the model, how long a cut took and into how many parts, the export format, and when something fails and where in the code. With them go the language, the theme, any campaign tags in the link you arrived by, and whether the launch-list box was opened. Nothing is read from your computer itself: not its screen size, processor or memory. No visitor ID is given out, and each count is stored on its own, without a cookie or your IP address.
