Remix of the shelf portion of this model: https://www.printables.com/model/280311-skadis-shelves
Meant for SKADIS Ikea peg board. Just a simple redesign of the shelf support to try and solve some consistency issues. These worked better for me than the original clips.
The author remixed this model.
The shelf support design was changed to better suit my SKADIS board. You may find it helpful if you are having issues with inconsistent hole sizes on the board.
