This improved crank features a thicker pivot pin for increased strength.
For maximum durability, I recommend printing it with 100% infill. Since this is a small part, the extra material and print time are negligible.
Three versions are included:
Countersunk (flat head) screw version for M3 and M2.5 screws – provides a flush, smooth surface.
Pan head screw version – easier to source in some regions.
The two flat head versions use M3 × 16 mm and M2.5 x 16 mm screws. You can find these at amazon.
