Improved Spool Holder Prusa i3 MK2/MK2S/MK3

This is a redesign of the spool holder that came with the MK3.

I just used Fusion 360 to extrude the frame clamp and add a filament guide, the hole is 5mm dia. so it should fit if you use 3mm filament.

The holder snaps on really nicely and will not move. Very easy to print.

Printed 2 in 11.5 hrs.
