A little Knob for the Pen-Holder of the Spherebot / Egg-Bot:
https://www.thingiverse.com/thing:1683764
Requires a M3 Nut and a M3 Skrew (needed anyway for the Egg-Bot). The Knob needs some space, so I used a little longer skrew. But the 'original' M3 for the Egg-Bot also works fine for Sharpies.
Rafts:
No
Supports:
No
0.2mm
Infill:
15
Notes:
I used a Prusa MK3S+ with PETG to print
0.2mm Quality Mode and 15% Inflill.
Should work fine with other settings as well. Just make sure its more or less precise to fit the nut.
