Make any .3mf U1-ready
Drop a .3mf from MakerWorld, Bambu Studio, PrusaSlicer, Orca or Creality Print — get back a U1-ready file: the foreign profile swapped for the real Snapmaker U1 profile, painted multicolor mapped to the U1's 4 slots, colors preserved. Runs entirely in your browser — nothing is uploaded.
Your file never leaves this page
No upload, no server, nothing stored — not the model, not its settings, not even the file name. The conversion runs on your own machine, so it's safe for paid models and no-redistribution files.
· Live colored preview before you download
Built for the Snapmaker U1 — and it can also retarget your file for other printers (Bambu, Prusa, Creality) or strip it to a clean generic 3MF.
Tip: the browser extension does this right on the MakerWorld/Printables download page.
