You can find many pegboard hooks at Thingiverse. But unfortunately in Europe/Germany, we are using a different style of pegboards.

So I came up with this simple solution, which was inspired by the hooks which came with my german board.

Hopefully someone find this useful. If there are any hints for improvements, just write it down in the comment section. Thank you very much!

It is designed for pegboards with a thickness of aprox. 0.9mm
