I got tired of having all of my koozies crammed in a drawer, so I went online to look for something to store them in. I saw a metal version of this selling for way too much money, so I decided to design and print one myself.
It uses #6 wood screws to mount to the wall. I used PETG, and if you plan to use it in an outdoor kitchen or bar, I recommend doing the same. Otherwise it can be printed in PLA. I only needed supports painted on the bottom edge of the front flaps (tree supports). Print with the open end up.
PETG (or PLA)
3 walls
Infill doesn't matter because the walls take up the entire space.
