Heres the last thing i did along with printing the ball joint. the ball joint is secret sauce though and i only shared it with ppl at the discord. Not it matter anymore cause i gave up. This is too much work i also dont have enough space in my new apartment.
Thats called a step down buck converter. you might need one if you plan on using batteries. i had to turn the screw like 10 times. Very important if you plan on using one.
