Hers my Deej volume mixer case! components used are;

• 1x Arduino Nano
• 5x B103 10K ohm slider potentiometers
• 10 M2*4 screws 
• 8 M2*8 screws

You can flip the face plate to get a smoother finish on the top, Base plate should be printed flat side up. If you have cracked bed adhesion the knobs can be printed with the tops facing down or you can use supports to print side ways.

As of now there's no place to mount the Arduino, you kind of chuck it in the case. but i will update the files when that is available, thank you for checking this out!
