Desk Mount Pen/Tool Cup

thingiverse

These are a simple implementation of the T-lock. I've provided STLs for both the male and female parts. I have also provided an example (which I use at my own desk / workbench) where I have a cup for pens, exactos, and a small ruler. I printed these using PLA. I'd recommend supports for the overhang on the female T-lock, but this can be avoided if you print the lock mechanism separately and attach it to the part.
