Samsung Galaxy Watch Ultra strap holder

The Galaxy Watch Ultra introduced a new style of watch straps. This model is a wall-mounted holder, designed to be the correct width to fit 1 or 2 normal sized 3M Velcro Command Strips for non-destructive mounting on a wall.

Each of the 5 slots can hold up to two pieces, for 2-part straps, or of course a single piece for 1-part loop-style straps.

I have included the STEP file to allow you to make minor modifications.
