Prusa spool holder upgrade

I'm a big fan of upgrades that improve solutions and don't destroy the original elements. I couldn't find a spool holder that satisfied me, so I made my own by modifying the original one. I wanted to remove the friction of spool rotation in a cheap and simple way. Did I do it right? We'll see :)

Parts needed:
- 2x 6805 2RS bearing, 25x37x7mm

Filament used:
- PET-G, DevilDesign (very low shrinkage)

Printing parameters:
- no supports
- perimeters 4
- infill 20%
- 0.20mm SPEED profile

I used very tight tolerances, please pay attention to the shrinkage of the filament you are printing from. The model requires no post-processing. The threads may seem too tight at first due to the seams, screw the nut in and out a few times before assemble. The thread diameter is 42mm.

IMPORTANT! Assemble the parts in the order shown below:

all parts you need:

step 1

step 2 (align the element with the hole)

step 3

step 4 (do not push too hard, the whole thing should move freely, check the hole position)

step 5 (do not push too hard, the whole thing should move freely)

step 6 (do not push too hard, the whole thing should move freely)

step 7 mounting on the printer

step 8 ready
