broke documentation when you silently migrated to 3mf

commit 2dad0ca removes the file linked in the docs and replaces the stl with a 3mf file. need to change file name in readme

Hey,

• Can you link where the docs broke? I don't expect a 3mf vs stl difference is an issue, it's difficult to track changes like that
• Can you expand on the lack of compatibility of 3mf on linux? As long as you have a slicer (eg. Prusaslicer, Orcaslicer..) it should be fine

the linux problems were just my ignorance, I was down one of these rabbit holes:
SoftFever/OrcaSlicer#6800
3MFConsortium/gladius#3

but I understand now how the migration was the correct decision.

#55

We can eventually add a note about the STL/3MF file interchangeability
