Update: now can print with no supports (xxxx_long version).
It holds the standard filament spool and it won't fall off. I use it, it works for me! I tried to design it with strength and not a hideous amount of filament or lengthy printing time, minimal or no supports (none needed with xxxx_long version). Fits on my Prusa Mini+ print sheet (see included .3mf file…).
[2024-11-28 Update]: I added .stl model / .3mf / .gcode files with (xxxxx_long) with a 10mm longer shaft that should work with wider spools (like Amazon Basics), better screw holes, and no supports needed during printing.
