Besides this model, you'll also need 1x CSD_Salzburg's "Universal Hook" to attach it to the Skadis. I've printed mine with PLA at default OrcaSlicer settings (3 wall loops, 15% infill density) on a Elegoo Neptune 4 Pro.
Unfortunately having started with the universal hook as a mount base instead of modelling my own mounting hooks makes this holder have a spacing of ~9mm away from the pegboard. TODO for version 2 would be to change the universal hook mount to instead be a pair of M2/M3 holes for T-nuts or just to add my own hooks.
FreeCAD file included.
