Heavily inspired by Martin's spool holder I remodeled all the parts so that I could tweak them. I know the 3D printing community loves a good hexagon but my eyes prefer round things so my models have everything rounded off. I still printed the components with the honeycomb infill and zero bottom or top layers where applicable to show off some hexagon love.
Printed using a Prusa MK4 - No Supports - No Brims
Arms - PETG - Textured Plate - 0.20mm layers - 20% Infill - 5 perimeters - No top or bottom
Bolt - PLA - Smooth Plate - 0.15mm layers - 100% infill - height modifier from 0-1.25mm with no bottom layers and 20% infill
Nut - PLA - Smooth Plate - 0.15mm layers - 20% infill - no bottom layers
Spacer - PLA - Smooth Plate - 0.20mm layers - 6 perimeters so there is no infill needed
Wheel - TPU - Textured Plate - 0.20mm layers - 4 top and bottom layers - 3 perimeters
Hardware Needed - 8 x 608 bearings (I got mine off Amazon)
