Here is an DEEJ that me and a friend designed for either a Arduino UNO or and Arduino NANO. (The Uno requires the deeper bottom part then the Nano)
We followed this guide for the DEEJ. https://github.com/omriharel/deej?tab=readme-ov-file
The idea was to make it clean and be able to have it all be an easy install. It was designed for the 75mm 10ohm slide potentiometers. The potentiometers have a good press fit, but for added strength we designed a back plate that both holds down the Arduino and the potentiometers. (Check part name for model version, same top part, same knobs, the rest have different parts)
Ideally the backplate is screwed down by m2.3 self tapping screws. (Also m2 or m3 will work)
If you cant source the screws some hot glue should do fine.
The bottom part of the case is held down by m5 screws. If you print the case at a good enough resolution there is a model of m5 screws that can be used to hold down the back part.
We intentionally placed the arduino deep in the case so that the cable will be a part of the assembly and its port should not be bent/broken and eventually start getting a bad connection.
The top piece is the same for both versions of the arduino board. Depending on what arduino you use there is a different bottom and mid support piece.
All parts can be printed without support if printed with flat part positioned down
