Afinibot A1 Carrier upgrade

thingiverse

The Afinibot A1 delta printer features notoriously sloppy linear bearings. I upgraded each of the three carriers with an extra bearing to eliminate play, and the result is nothing short of remarkable. Three LMB6UU linear bearings are now required. I stumbled upon this modification online, but haven't had a chance to try it yet: https://www.thingiverse.com/thing:36330. The added bearing housing is slightly longer than standard to accommodate differences in bearing sizes across various brands. When printing the upgraded part, I used regular PLA filament with thicker walls and 18% infill. A slight increase in temperature, combined with a tighter extrusion width and slower print speed, yielded a stronger but not necessarily nicer outcome.
