I am designing a crank system for my 3D printed music box to turn the music cylinder. Since the music box cylinder is large about 30 cm diameter, the effects of backlash of only a degree or two is magnified.
How can I use lego gears to design a crank that increases torque and decreases speed with practically zero backlash?
I know I may receive some flack for this, but I am fine with a solution that requires some glue or 3D printed parts or springs, but I would prefer if it was all Technic.
Thanks!!!
