Low-Friction External Spool Holder

Decided to design a freestanding version of my bearing-mounted Skadis spool holder after a friend wanted to try printing soft TPU and didn't have a Skadis available. Works beautifully with my A1 (with extruder mod) for printing 85A and 83A while sitting on a shelf above the printer. Requires two bearings which press fit, works with any 1Kg spool and prints on every Bambu printer including the A1 mini. Any questions/issues let me know! Boost MeBoosts always appreciated, all points go into the "keeping me in filament" budget.
