Prusa Filament Guide
thingiverse
This is a snap-in filament guide for a Prusa MK3s (unknown if it will fit other versions) I like to feed filament from a table-mounted spool holder rather than from the top so I designed this, using some parts from D3D_Designs filament guide: https://www.thingiverse.com/thing:3129612 It snaps in to the hex hole at the top of either side of my MK3s. File to fit or glue in place if needed. Requires an M3 SHCS and 608 Bearing. I tapped the hole for better threads but I think you could probably glue the guide holder on if you had to (make sure not to glue the bearing)
