Horiztonal Filament Spool Holder

I had a need, due to confined enclosure space, to mount my filament spools horizontally. This is for my Prusa MK3.5, but fits any Prusa MK3/4.

Depending on the type of filament, if may be prudent to slice a small portion of the bearing section and print to check for dimensional tolerances.  I printed with Fiberon PA6-CF20 for no other reason than I was too lazy to change filament; it was a snug fit for the bearing but it fit.  Due to weight load of spool, and being located in a potentially heated chamber, chose a filament that can support your specific environment.



Version 1: vertical spool - slightly obstructs Nextruder cable.

Version2: horizontal spool

• glue-in-place spindle pin (glue to spool spindle, not bearing, apologies for stating the obvious)
• Requires 608 bearing (print-in-place works as well)
