Machine for lifting balls for Gravitrax.

Print the parts and glue them together. You need a N20 gear motor that is rotating at 60 rpm or less.

I used a ball bearing at the bottom. The size is 12x6, width = 4 mm.

I use a power-bank to power the motor. I soldered an old charging USB cable to the motor.

The mechanism works well - This is the second iteration on the design.
