1/4" "D" shaft knurled knob with "scroll assist" bearing

thingiverse

I designed a new knob for my i3x that had an off center dimple to help with scrolling through my printers options, and that was cool and all. But I had a little bearing (R4Z) laying around that I wanted to use in something. I realized that I only had to modify my knob a little to marry the two, so this was born! I'll also put the original "dimple" knob in the file section in case anyone is interested. It's split into 2 files, one for the main knob, and one for the dimple. That way you can print one as one color and the other as a different color.
