Optimized spool wheel for Prusa ENCLOSURE -IKEA LACK-
thingiverse
This thing is an optimization for the "Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table - Prusa Research" (https://www.thingiverse.com/thing:2864118). My spool wheels had much friction in the bearings. So i decided to make ball-bearing mounted spool wheels. Now they are turning very well with very low friction. You just have to replace the spool wheels and the axis of the mentioned spool holder above. I took those ball bearings: https://www.pollin.de/p/kugellager-442039 You need 2 of them per wheel (8 for all wheels). Outer diameter: 13,5mm Inner diameter: 6,3mm Width: 5mm Printed with my Prusa i3 MK3S, the ball-bearings and the axis joint fit without any glue.
