KEYper Systems - Mechanical Access Peg

Instead of paying five bucks a pop for one of these, I modeled one up and just print them myself. They work perfectly and seem plenty sturdy enough for how it's used. I printed with PLA pro, 60% infill, 80/40 speed, and standing upright with the gear end down on a raft with supports.

In the picture, the gray pegs are the printed ones and the white peg is the original.
