Filament insert for 8mm rod / 57.5mm spool hole - Migbot

SummaryMy next simple improvement for my Migbot incarnation. Standard spools holders are basically 2 x 8mm rods that connect together 2 acrylic sides. They are ugly and not practical at all. This small insert will help make filament extrusion smoother. It is very material-economical design. Takes less than one hour to print 2 of these (you will need one for each side of the spool). It fits perfectly with very little tension into popular filament spools with ~57.5mm holes. There are 2 files attached. OBJ files has better resolution. ..Print SettingsRafts: Doesn't MatterSupports: Doesn't MatterResolution: 0.2mmInfill: 50%Notes: Printed with PLA / 220 nozzle / 60c bed.
