3D tools

Small, fast tools for 3D printing. Each one runs in your browser and downloads a file your slicer can open or inspect - no account, no upload.

Utilities

Work with models and links you already have. Files never leave your browser.

STL Splitter Split an STL, OBJ, or 3MF that is too big for your printer. Cut at any angle, add dowel or threaded connectors, download print-ready parts. Open tool

STL Doctor Analyze STL, OBJ, 3MF, GLB, or GLTF models for boundary edges, non-manifold geometry, degenerate triangles, overhangs, wall thickness samples, dimensions, volume, and a printability score. Open tool

Type, slide, download. Each one makes a printable model from scratch in your browser.
