Roll axle with bearings for ender 3 pro

thingiverse

Hi everyone, I designed these parts to have the roll of PLA on bearings to allow a smoother feed to the printer. I am new at this so I designed it for the rolls I have, which are all 6 cm wide. All parts are printed without support, although I use brim as a fixing help specially for the bearings, since the little balls need a little bit of extra support. For the bearings, axle and nuts I used 20% infill since they are exposed to some force. for the rest of the pieces I used 10%. Use at least thickness of 3 for the walls of the bearings. When setting the bearings flat on Cura or the slicing SW you use, make sure you put the flat side of the bearing balls facing downwards. Cheers!
