This simple rack is designed to hold up to 20 Apple Watch straps and can be mounted using two M4 x 16 screws.

For straps which have a fastening, like the Sport Band or Sport Loop, I recommend only placing a strap in every other slot, so one rack will hold 10. Slimmer straps like the Solo Loop will fit closer together so can fit in every slot.

The ends are designed so that multiple racks can be mounted together to form one consistent rack.

I printed mine in PLA with a 0.28mm layer height, with the back of the rack on the build plate (so the slots point up like a toast rack).
