Cut Craft (3D PrintCraft)

What is Cut Craft (3D PrintCraft)?

Cut Craft splits a 3D model that is too big for your printer into parts that fit, and adds joints so the parts go back together. You upload an STL, OBJ, PLY, 3MF, GLTF, GLB or FBX file (a sample cat model loads by default), choose your printer bed from presets between 180 and 420 mm, and place one or more cuts left to right, top to bottom or front to back. You drag the cut plane in the 3D preview, tilt it to any angle, or let the tool suggest cuts for the bed you picked; parts that still do not fit are flagged.

Parts can join with a butterfly key that prints flat, dowel pins or magnets, or no joint, with a joint size setting and a fit clearance of 0.2 mm by default and tight, normal or loose presets. There is a small fit test coupon to print first. You can orient the model on the bed, scale it, spread the parts apart in the preview and save the project as a file to reopen later.

Downloads are each part and the keys as separate STL files, all parts in one 3MF, and an SVG assembly sheet. Cut Craft is free with no account, one of two free generators on 3D PrintCraft, a small Russian site whose other tools need a paid plan. An EN switch translates most of the controls, though a few labels stay in Russian. It suits anyone printing large figures, cosplay parts or signs on a small printer.
