WARNING!: I think the magnet might be messing with the electronics in the pen as it has been acting weirdly after i started using the holder. Ive made a V2 where the USB-A nub is thicker and should hold better in the port without the magnet.

12.06.2026: Added model with thicker USB-A nub

Requires 5x10x2 magnet. USB-A dock is pretty loose and could be made thicker.

Friction fit seems to be sensitive to different materials. If you have Onshape you can copy the model with the link below.
