This is a custom designed filament spool bearing rack for the Monoprice Select Mini 3D V2 printer.
I designed it because I didn't like the loud clicking that the feeder motor made as it tried to rotate the spool against the stock metal rack. This design fits over the existing rack so no printer modification is required. It was designed for Monoprice brand filament spools. It will allow any 4.5 cm and up inner diameter spools to slide over it. The spool width is 7.7cm.
Uses 2 x Universal standard size 8x22x7w bearings:
The print contains the main piece and 2 optional end caps if your bearings fit loosely. Mine did not require these as the bearings press fit after printing.
Dimensions:
Length = 93mm
Height = 45mm
Width: 29mm
NOTE: Make sure your slicer matches these dimensions prior to printing or nothing will fit.
