Printable 608 Filament Bearing

thingiverse

Revise your previous design for a bearing that resembles a 608, using 3mm lengths of 2mm filament as rollers. This updated version features enhanced precision with an estimated 0.5mm thrust and wobble, potentially further reduced through careful sanding and cleaning. The key to success lies in cutting and shaping these tiny ABS rollers accurately, ensuring they're flat rather than pointed for optimal performance. Be mindful of jig dimensions and adjust accordingly based on your printer tolerances. Assemble the bearing by placing the rollers around a tall core, adding the large short pieces, and securing with ABS cement. Don't forget to weigh down the center piece while glue sets, and add a drop of oil for smooth operation.
