As I looked for a simple Skådis pin to hold my steel ruler, I wasn't successful, so I created my own. In the end there were three versions. One straight and two slanted (up- and downwards).
To attach the pegs to the board the T-Nuts for Ikea Skadis Pegboards system from 6d6178 are used.
Print with support activated and the backside of the pegs oriented to the print bed.
The author marked this model as their own original creation.
