My first model made by me. This is version 1 which probably needs reworks and modifications. I am working on system which will secure arduino without need for somekind of glue or cable ties.

This project will allow you to controll individual volume of programs. For example:

1. Knob- Master volume
2. Knob- Discord
3. Knob- Chrome
4. Knob- CS:GO, GTA V, R6 and so on…

Audio controller is using DEEJ software, Github ( https://github.com/omriharel/deej/ )

What is needed?:

• x4 M4 inserts
• x4 M4 screws (max +-20mm long)
• Arduino nano (or something similar but you have to modify back stl model)
• Cables
• x4 potentiometers 10k Ohm with secure nuts [100k Ohm will work too]
• x4 potentiometers knobs
• Minimal soldering skills
• Glue gun (not required)

You will need to print:

1. Front panel (version you need) [+-20g]
2. Body [+-100g]
3. Back panel (version you need) [+-22g]
4. Knob (optional)

Printed with 6mm nozzle 2mm layers. I recomend to print front and back panel on glass for glassy look or on textured printbed for nice textures. I printed Body stl with supports only on rounded corners of the body and on the bottom where there is 90° angles.

Dimensions: 173mm x 61mm x 60mm

Tutorial which might help by: Mad Mod Labs

I created panels without holes if you are using diffrent size of potentiometers or microcontollers

You could also use some pennies to make model weight more, by wrapping some pennies in electrical tape and securing them inside.
