Lockable Pegboard Rivet

A lockable pegboard rivet for 1/4" pegboard.

This is based on similar designs I found on Thingiverse, but tweaked to my liking.

* [Pegboard rivet](https://www.thingiverse.com/thing:4541970) by [Jon Sanders](https://www.thingiverse.com/jongsanders/designs)

I liked the general design of Kenneth Stout's rivets, but they seemed too long to me; stuff I mounted with them was not held tight against the pegboard. I liked the locking feature of Jon Sander's rivets, but the hole seemed too big for 1.75mm filament, and I wasn't fond of the shape.

I designed mine with the same head dimensions as Kenneth Stout's, so they should be compatible.

Things designed to accept these rivets should be made to these specifications:
* Thickness: 1/8" / 3.175mm
* Hole size: 6.5mm (a bit bigger than 1/4")
* Counterbore diameter: 9.8mm
* Counterbore depth: 1.6mm
