Motivation:

I got inspired by Skizhoo (https://www.printables.com/de/model/687017-creality-k1-filament-spool-holder-with-ball-bearin) by the spool holder and found a different version from Michael F (https://www.printables.com/de/model/687245-creality-k1-spool-holder-roller-skateboard-bearing), who offered .stp-files. So it was easy for me to remix it to a more compact version for me.

Print Settings:

Standard PLA, 0.4 mm nozzle, 0.2 layer height, 15% gyroid infill, 200mm/s speed, 2-3 wall perimeters

Standard zigzag support with 20% density, both disabled support roof and support floor (easier to remove)

Brim with 4mm width and 0.15mm distance (easier to remove)
