Modified Prusa i3 MK2 Spoolholder with ball bearing

thingiverse

I modified the original Prusa i3 MK2 spoolholder by adding ball bearings to improve its functionality. The added ball bearings enable the spool to unwind more smoothly. Additionally, they prevent the spool from wobbling while unwinding due to the two ball bearings on each spoolholder. I also included a printable ball bearing in case users don't have one available. To assemble this modified spoolholder, you will need to print four parts: Spoolholder_right, Spoolholder_left, Axis, and Ball_Bearing (optional). Print Settings: Printer: Prusa i3 MK2 Rafts: Not required Supports: Yes Resolution: 0.2mm Notes: You may need supports for the cutouts of the ball bearings. Post-Printing Instructions: Remove all supports from the printed parts. Place a ball bearing in each cutout. Insert an axis through the corresponding hole. Repeat steps 1-3 for the remaining ball bearings. To remove the ball bearings, push something through the hole on the back. The axis will fall out.
