Discord push to talk foot pedal

If you don't want to use voice activation on discord and a ptt key is clumsy during gaming, maybe this foot pedal will help.

This pedal holds a arduino pro micro with the ATmega32u4 chip. 

This chip allows the arduino to work as a usb keyboard. The idea comes from the user tactoad on instructables :

I used the same electronics and code as is referenced in the link above. The only adjusting to the code was adding the keyboard libraries  to get it to work. I also changed the input to KEY_F13 to use a key that does not exist on my keyboard, see the arduino keyboard reference here :

The push butten used is this kind (7mm thread and total 27mm length)(Not affiliated)

Hinge needs a 5*40mm bolt.

Backlid needs 3*5mm bolt

Prints in about 2.5 hours on the mini

The butten is screwed in with needle nose pliers, you can adjust the depth to change the engaging point. Screw in in from the outside first to loosen the thread a bit, than from the inside.

If the thread breaks, glue the button at the right depth.

Optionally you can install a little spring between the pedal and the body, if the button needs help pushing the pedal back up. 

Body should be printed with the 7mm threaded hole on the built plate without supports

Final note, there might be a danger in this device, if you create a habit of pushing the pedal while talking, maybe be extra attentive while using a motorvehicle.
