Filament Guide
My MK4 gave me the idea of a filament guide, and it is a great idea. As many of you have experienced, sometimes a new roll will allow the filament to slip off to the side of the roll and jam up the printing. The MK4 has a guide, but it is screwed on (so not movable) and needs a Teflon sleeve because it is so high that there is a very sharp bend to the filament when a roll is nearly finished.
So, I designed a guide that has a few improvements:
1) It slides on the roll-holder arm onto the ribs to whatever height you need
2) It has a slot in it so you can feed or un-feed the filament through the eyelet at any time
3) When a smallish part is being printed, the angle the filament passes through is very slight, so no Teflon sleeve is needed.
Since the MK3 and 4 both use the same roll holder design, it works on both machines.
