Optimized spool wheel for Prusa ENCLOSURE -IKEA LACK-

thingiverse

This thing is a game-changer for the "Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table - Prusa Research" project (https://www.thingiverse.com/thing:2864118). My spool wheels were experiencing excessive friction in their bearings, which was a major problem. So I took matters into my own hands and designed new ball-bearing mounted spool wheels. The result is impressive - they're turning smoothly with minimal friction. To achieve this, you'll need to replace the original spool wheels and the axis of the spool holder mentioned above. I used these high-quality ball bearings: https://www.pollin.de/p/kugellager-442039. You'll need two per wheel, which means a total of eight for all four wheels. Here are the key specs: * Outer diameter: 13.5mm * Inner diameter: 6.3mm * Width: 5mm I printed these components with my trusty Prusa i3 MK3S, and I'm happy to report that they fit together perfectly without any need for glue.
