Cap Rack (Extendable with Dovetail joints)

I designed this extendable Cap Rack design when I was looking for a good solution to store and display all my caps without buying the expensive solutions online. I created a system that can be clicked together, so that only 1 screw is needed at the top piece to mount it to whatever you mount. (I added mounting holes in each part, so you can use multiple crews if necessary, or just use sticky tape)

Caps are mounted by folding the back part of the cap inwards and sliding the top “nob” of the hat in the circular part of the rack. The arm will hold up the hat and prevent it from falling out of the rack.

The Cap Rack consists of 3 parts.
- A top part (female dovetail on bottom)
- A middle part (male dovetail on top, female dovetail on bottom)
- A bottom part(male dovetail on top)

I you only need 2 hat rack spaces, you can easily print only the Top and Bottom design and click them together. If you want, for example 8 hat spaces. You can print; 1 top part, 6 middle parts and 1 bottom part. If you buy any new caps, don’t worry! You can easily print a new middle part and add it to the rack.

The screw hole has a diameter of 10mm, so that it the maximum screwhead size that can be used.

The result is in the photo’s is printed on Ender 3 with Glass bed.
Used a 0,4mm nozzle, with a layer height of 0,2mm. Infill used is 25% Hex.

Please let me know if you require any adjustments or improvements, I will be happy to help!
