This is a remix of the excellent cups Daboo Designs made: https://makerworld.com/en/models/132640
Theirs used mini bolts to attach to the multiboard, but I got annoyed trying to attach them so I threw on the pegboard connectors.
It's a pair of cups, 1.5in (38.3mm) and 2in (50.8mm) for holding small items like pens, etc.
Print:
0.2mm layer, 3 walls, 15% infill
These can print without supports, but I painted on minimal support for the bottom peg.
