Prusa i3 MK3 Filament Holder arm

This is an arm that can be printed twice--once in mirror--and attached to the top of the Prusa i3 MK3 (and maybe the MK2 series as well) that will allow you to store up to three roles of filament on top of your printer at once. All you need is a 12 inch steel pipe and end caps for it.

The pipe goes through the first arm, then through the second arm, with the caps screwed on the ends to keep everything in place.

Make sure you print one normal and one mirrored, so you can put one on each si
