Crank Handle for the Cyclone Marble Machine

thingiverse

After printing the Cyclone marble machine with silk PLA, I discovered that the winder for the spiral breaks easily, as it needs to be printed in a way that creates a weak-point. I also imagined a crank as a nicer solution for this incredible model. So I took a nice model for a crank, modified it to fit the size, separated the pin so that it can be printed sideways, and modified the handle so that the edge can be rotated freely. Printing instructions: 1. Print the hex pin using your strongest filament (PLA+, for example). The color doesn't matter, as you don't see it after assembly. Use 50% infill. No support. Skirt. 2. Print the handle with support! Use tree structures. Use 20% infill. 3. After printing , apply a bit of force to release the end of the handle so that it can spin freely.
