I love these holders and wanted to make them for the multiboard.

I remade these in two different variants.

1. Screw - These are threaded for the large hole size and should screw in to just tighten at the correct angle with the board, if hung in the standard format
2. Weight bearing snap - These are designed as a push in to hold more weight firmly

I find that printing the weight bearing snap variants at 101% helps with tightness.
