Lifting machine for Gravitrax

thingiverse

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.
