Prusa Inline Spool Holder
by HLMAX, published
Another spool holder!
This is a spool holder that clips onto the top of a Prusa. Desiged for compact, 90mm wide, 2kg spools.
Clips on easily and easy to remove. The filament is dispensed inline with the X axis, so it comes off the spool easier with less flexing and rattling.
Press two 608 bearings into bearing retainers. Two size of bearing retainers are provided, for 40mm and 30mm spool holes.
Sandwich the spool between the retainers with a 150mm long 5/16 thread rod, held in place on both sides by 5/16 nuts.
Screw the Spool Arms to the Clip-on Base using #4 X 1/2" countersink wood screws.
Gentle spread the Clip-on Base and clip it to the top thread rods of your Prusa.
Place the spool assembly on top of the Spool Arms. Secure it to the arms with a 5/16 nut on each side.
I print my parts 2 perimters, 2 solid layers and 0.3 fill density.
