Prusa i3 MK Filament Spool Holder ClipOn

The Prusa i3 MK is a great printer, but the filament spool holder could be better.

I redesigned the original to:

• Support a tube instead of taps to hold filament spools... and more than one spool support.
• Easy attach the Prusa frame with ClipOn

Filament storing holes for holding unused filaments. The tube I use is standard electrical 20mm PVC tube that snaps into the holder. In case you like the original tab based style, I included models for that too (no tube needed).

For tube holders, the left and right holder is identical, just print two.

If you need another tube size, leave a comment and I will upload model for that size.

Based on the Original Prusa i3 MK open source files found on GitHub.

New MK3 style design: Prusa i3 Spool Holder, Single Side ClipOn

Update:

• Added holder for 22mm OD tubes.
• Added holder for M8 Threaded Rod.

Print Settings

• 0.20mm layer height, 25% infill
• 2 perimeters, 3 top and 2 bottom layers
• No support or elephant foot compensation needed

Preferred material is PET-G, but PLA can be used. ABS will properly have corner warping problems due to the size.
