mini 3 Button Keyboard with RotaryEncoder

My version of a min 3 button hotkey keyboard or streamdeck , yes it cloud be smaller but this size fits nice on my desk.

It uses Acrade buttons from Pimoroni and an Arduino ProMicro (32u4)

Update:

• I added a RotayEncoder, a very simple one like you can buy for 2€ or less per item on the internet. It does not have a PCB so I had just to drill a hole in one corner to mount it in the printed case. I still miss a nice knob design for it.
• Updated the Arduino Code to 4 button and encoder and AHK file too, it uses the now the some Media Control Keys.
• Added the knob, I cut the encoder shaft so it's nicer length.

You might have to flip the parts by 180 degree, ctrl+L in Simplified 3D

so the flat faces are on the bed no need for support.

Assembly:

Use hot glue to glue the Micro to the adapter plate and the bottom plate.

• close the case (top and bottom, it's easy to open)
• put the Micro in the adapter, put a little hot glue through the button hole next to the USB hole, press the adapter with the micro in the glue make sure the USB parts line up.
