I was getting cramps in my hand cleaning dozens of pot knobs, so i made this little cleaning helper. I hope it ends up being as helpful as it was for me, enjoy!

The holder is modeled for a standard 6mm pot shaft so it should suit the most common of knobs you find around, but, just in case i added the .STEP file so you can modify the measurement to fit your knobs.

No special printing instructions needed, i printed mine with generic PETG with this settings:

0.20mm layer height

0.44mm layer width

3 wall loops

20% cubic pattern infill

Print time 24min 10g on a Bambulab P1S.
