IN PROGESS - not printed yet!
I think the 10mm long hooks by Make Anything would work well for this, as they won't stick out too far. (https://thangs.com/designer/Make%20Anything/3d-model/EZPZ%20Pegboard%20Hook%20%2F%2F%2010mm%20Hook%20Type%20B-945299)
Theoretically could also be used with the pegboard holes in a Multiboard.
Meant to hold on to the modular drawer system by LR3DUK on cults3D (https://cults3d.com/en/3d-model/home/fast-print-modular-storage-system).
The author remixed this model.
Removed the Skadis hooks from the back of the original files and replaced with holes to be mounted with small/short pegboard hooks.
