The remix differs from the original by having back hooks (mounting clips) for the Skådis panel.
I took the back hooks from here: https://www.printables.com/model/662066-skadis-skadis-ruler-peg, I like that it fits very snugly on the Skådis panel. You can ungroup the model and delete the unnecessary hooks.
