re-usable pegboard hook

I really liked the look of the pegboard hooks used in this model. I wanted to use them in a different project (https://www.printables.com/model/300932-alternate-pegboard-holders), so I sliced off the dovetail part. Now that I have it in my library, I might use it to peg-board-ify other things.

I included a photo of just the modified hook. I printed it first to see if it would work on my pegboard before committing to print a larger item that included it.

I used Prusa Slicer to modify the STL and also to combine it onto an unrelated part.
