BallBearing spool holder for (Un)orginal Prusa Drybox

prusaprinters

I didn't like the friction of the steel bars, it was kinda hard to spin the spool even by hand..So here is my mod: ball bearing spool holder for (un)Orginal Prusa Drybox.The mount holes are for original, 18mm, bars.There is a version for 20mm bars - "WALL_beam_20mm.stlPRINT:For one spool you need to print 4x PIN.stl, and 4x WALL.stl (Total for 5 spools: 20 pins, 20 walls)BUY:For one spool you need 4x ball bearings 608, (Total for 5 spools: 20 bearings)Any 608 will work (608, 608z, 608zz, 608rs …).For best experience, add this one too: https://www.printables.com/model/624410-ptfe-converter-6-to-5-spools-for-unorginal-prusa-d   V2: Added second version after battle-testing this modelv2 is more sturdy, distance between bearings is bigger, so the spool sits better “in the saddle”, this fixes the issue with very lightweight spools with not much filament left, that sometimes were pulled out of berings when nearing end of spool. Also the hole for steel bar is bigger, from 18.30mm to 18.50mm On my V2 prints you can see embedded numbers for spools, this makes it easier to see which holders relate to which spool, thats usefull when you take out everything from inside of dry-box, and you start to re-fill whoole box. Thoose are made with “add negative part→ text” in slicer, example one is available as .3mf  PS: There exist a remix, that uses m3 screws to secure parts, you can use that if you're paranoid ;)
