Intuos 3 Grip Pen Holder

I was mostly just fiddling with OnShape to teach myself its ins and outs, so I decided to replicate the Intuos 3 pen holder for the grip pen (standard or special edition). Pleased with the way it turned out.

Update: Made the opening a touch larger, and the hole a touch higher to ensure better pen stability if you're at a slight incline (drafting table).
