Prusa MK2/MK3/MK3S TPU Ball Bearing Spool Holder REMIX

thingiverse

This is a remix of the Prusa spool holder that uses 608 bearings. I made the mount 10mm longer so it is more stable. Here's a video tutorial on how I make it: https://www.youtube.com/watch?v=YTorSRpJtqQ I recommend to print tire at 101% otherwise it won't fit 608 bearings well. Also I printed Axis Nut at 94% otherwise it won't fit the mount, also print the Bolt at 97%. This ball bearing mount allowed me to get much faster speeds for TPU flexible material around 200mm/s with maximum volumetric speed of 8mm/s. I don't think it will improve speeds much for harder materials like PETG, PLA, etc... This spool mount is great since you can adjust it to fit 0.5kg, 1kg, 3kg, or even 5kg spools on top of the printer, saving space. I made the mount longer because I intended to use it with 3kg spools.
