Your files stay with you
Every tool does its work on your own computer. Client parts, unreleased designs, a scan of your face: none of it goes to a server.
Real sizes, in millimetres
GLB comes in metres, FBX in centimetres, and OBJ or GLB exports often lie on their back. We fix both before you download.
What we don't do
No AI model generation and no slicing. Use a generator like Tripo or Meshy, and a slicer like Bambu Studio, PrusaSlicer or Cura.
