2040 spool holder for Prusa MK3s Bear edition or other printers

thingiverse

UPDATE 2020-11-05 : There was some interferences between extruder and spool holder while printing high pieces on my PRUSA MK3s Bear upgrade. The V2 files are 10mm higher then the first version for more clearance. Also, I have enlarge the guide for the same reason : filament was forced to sharp curves while printing high pieces... Finally, the V1 one pieces are tough to snap-on the frame, so I remove the snapping flange on the V2 pieces. Anyway, screws are holding the thing quite firm... ______________________________________ This is a remix from : https://www.thingiverse.com/thing:3551045. thank you for the design ! It's a spool holder that fit 2040 aluminum frame, like the frame of a Prusa Bear edition... I have replaced the clamps by holes for bolts and drop-in T-nuts. So no needs for inserts that I didn't have close at hands... I have include bearings spacer so that you can tight the bearings in sandwich with no worry. If spacer are not used, you should use nylon hex nuts to let some slack on the bearing... Hardware needed : 4x 608 bearings 2x threaded rod, 5/16 in or M8, about 200mm long min. 4x 5/16 or M8 nuts (and washer if you want) Enjoy !
