Bambu Lab Side Spool Holder

This is my proposal for a slim side mounted filament spool holder with simple bearings.There are five 3D printed parts needed:1x main bracket1x spool roll1x bearing spacer1x inner end cap1x outer end capUsed printing parametersPLA0.6mm nozzle0.2mm layer height4 wall and top/bottom layers50% infillMost other needed parts are fairly standard1x 185mm aluminium tube, 8x1mm length, i.e. 8mm OD, 6mm ID2x bearings type 608 8x22x7mm2x M3x20mm button head screws with washers1x 6mm plastic dowel1x 3,5x35mm self-tapping screwAdditional modificationsReplace the standard 550mm PTFE filament tube by one with 800m lengthAdd a second tube fitting to the outer end of the rubbery tube ductI'd be glad to receive some feedback or comments for further improvements.The shown setup is currently undergoing testing on my Bambu Lab P1S. Update:Added STL files for holding 2kg spools with extra 50mm width.This is untested so far, please try at your own risk.Just print 1x wide roll and 2x wide bearing spacer and u
