Introducing my custom  modular buttonbox based on SIMHUB.

Every single part is detachable so you can add your favourite mod onto the frame of the buttonbox.

You will need:

• 28 M3x5mm screws along with 28 M3 heated brass inserts for the button box and the LED panel;
• 4 M4x20mm screws with 4 M4 heated brass inserts to attach the button box to the table clamp;
• 1 MAX7219 8bit 7 segments LED Display;
• 2 WS2812b 5V ARGB LED strip; 
• 1 arduino micro 5V;
• 12 16mm push buttons;
• some wires;

There is no need for arduino sketch if you are using SIMHUB programming.

The connections between components are indicated in SIMHUB arduino setup screen.

The LEDs and the 7segment don't have any support for installation due to the different designs that are out there. To install them I used hot glue. If you want you can modify 3d model to accomodate your hardware.

The LED module is secured to the clamp using M3 bolt and nut with washers to ensure easy rotation.
