Print it support-free, in any slicer

Rotate a part however it prints best, and Support Fins bakes the breakaway supports right into the STL. It prints the same on any machine, in any slicer, with supports turned off.

1. Open an STL. Drop it anywhere on this page.
2. Rotate it. Red marks every surface that needs support.
3. Export. Fins come baked in — no slicer supports needed.

Opening the 3MF, Bambu Studio and PrusaSlicer may note it has “no config” and load the geometry only — that’s expected. The file is pure geometry with no slicer profile baked in, so it opens the same in every slicer; your part comes in correctly oriented and sized. Just slice with supports off.

Nothing is uploaded. The file is read inside this tab and never leaves your machine.

Free and open source. If it ever saves you a print, buy me a coffee ☕.
