List of parts:

Qty	Part	Notes
2×	NEMA 17 stepper motor	I used 17HS4401S 1.8A. They are slightly too large and don’t fit perfectly, but with some modifications, you can make them work.
2×	GT2 pulley, 20 teeth
2×	6002 bearing
2×	GT2 timing belt, 200 mm (200GT2)
2×	Stepper motor driver	A4988 or ATD5833 (both work fine)
1×	Microcontroller	Arduino, ESP, or similar (I usedESP32 Uno).
—	M3 screws	Various lengths: 6 mm, 10 mm, 15 mm, 45 mm.

Personally, I used an ESP32 Uno with ATD5833 drivers and 1.8A NEMA 17 stepper motors.
Using the Bluepad32 Arduino library, I programmed it to be controlled with an Xbox gamepad.
Once I finish, I’ll share the code and wiring schematic as well.
