Hand 1-Way Crank Marble Run 003 - No Motor Removal

Boost MeThanks so much! A boost would be greatly appreciated if you enjoyed my creation.

 

I Just built the Marble Run 003 Components Kit from Bambu Lab and was excited for my toddler and pre-schooler to play with it. Although they loved watching it go, they really wanted to control the elevator. So I decided to look for a manual hand crank to print for it and found this great design by Pretzel 3d (https://makerworld.com/en/models/50487#profileId-52241). Unfortunately, I was faced with some problems: the ones I found required removal of the motor, or were a weird fit; and my kids would get confused and sometimes send the elevator backwards which would jam some marbles underneath the elevator. So I decided to design a one way clutch type model which can work without removing the motor, can't go backwards, and is just fun to play around with. This all could not be done without the help of some models listed as being remixed from. I hope you enjoy!
