How it works
Type what you need in plain words — sizes in millimetres if you have them. STLsmith's AI converts it into parametric geometry with FDM rules baked in (2mm minimum walls, real M3–M5 screw clearances, no-support orientation where possible). Preview it in 3D, refine by chatting (“5mm wider”, “M5 instead of M4”), and download the STL for Cura, PrusaSlicer, Bambu Studio or any other slicer.
What you can set
Every dimension is yours to choose: overall size, thickness, hole diameters and positions, counts and spacing. The first three forges are free with no account, and every generated STL downloads in full.
