I made this to hold my hex bits in a compact manner. I used the pegboard mount so I can easily unmount it and place it somewhere else. The pegboard mount is placed on one side so it can be printed without supports.

Any print settings that work for multiboard parts would also work here as well.
Mine is printed on a 0.6mm nozzle with 0.36mm layer height, 2 parameters, 20% infill and without supports.
