Filament spule rolling holder

thingiverse

Roller holder for spools is 200mm in diameter. You can print directly from it and dry when printing something long. The rollers spin on 634 bearings that are screwed with an M4 nut. Each base has a screw M3, during printing you need to organize a pause to insert them. Everything is assembled to the bottom, you will have to remove the BOM to screw it in. In 99% of cases, the spool is not touched by anything, the carriage passes above, but still, if you hit the minimum settings at X, the nozzle will touch the spool, so be careful. On the photos it is clearly visible. SolidWorks16 sources are included.
