Arduino Stream deck

Homemade stream deck made with arduino pro micro and some mechanical switches and one poteciometer.
And of course with Bambu 3d printer :)

Homemade Elgato Stream Deck made with Arduino Pro Micro and some mechanical switches and a potentiometer and of course with a Bambulab 3D printer :)

To assemble the model 12 mechanical switches and a potentiometer are needed I used a 10K one

Of course an Arduino Pro Micro which you can get on Aliexpress for about 50 CZK

And the printed attached models I recommend using PLA or PETG

A carbon fiber patterned mat was also used also from Aliexpress for approximately 220 CZK

I recommend printing keycaps at a layer height of 0.10mm and the rest at 0.15-0.20mm depending on your preference for detail and print time

Also needed are 4x M3x2 screws + 1x M3x10 screw

There is a prepared hole at the back for the Arduino's USB C port

Optionally also a knob for the potentiometer and a USB C data cable

And of course C++ code for Arduino this depends on what functions you want your stream deck to perform

I had custom stickers made for the keycaps you can print them on your 2D printer on special paper or on plain paper and cover them with clear tape (that's a last resort)
