Hanging Watch Display

I have several watches (too many), some of which need access to sunlight for charging. Instead of leaving them on a tabletop, I designed this hanging rack/display. Since I could increase or decrease my collection, I wanted it easily modifiable. It's made up of the following printable item:
- Hanger - This has 2 holes at a right angle to the hanger so it can be attached to a shelf or top of a cabinet.
- Spacer - I wanted to be able to adjust the spacing between watches, so I made a parametric spacer that goes between each holder. They are attached using triangular pins.
- Watch holder - The bottom of the holder has a curved "french cleat" that snaps into the hangers and spacers. (I also CA glued the bottom of the holder to the top of the mount to eliminate a gap, but that's just cosmetic.
- Triangular pins to hold everything together. I do NOT glue those in. They have a good friction fit.

I print the holder on its back with no supports. I print the hangers and spacers on their sides wi
