NEMA-23 Motor Finger Crank

I recently upgraded from a belt drive to a screw drive on my printer's Y-axis. This necessitated a more powerful motor, so I opted for a dual shaft motor with a protruding shaft at the rear as well as the front. The manual crank attached to this shaft allows me to turn it by hand, facilitating tasks such as leveling the print bed and working on the undercarriage. The crank fits snugly (requiring a screwdriver to pry it off) and enables effortless motor rotation with my finger. Initially, I printed the part at 50% infill, but unfortunately, the section that grasped the motor shaft proved fragile and didn't last. To rectify this issue, I printed the new version solid, and it has been performing admirably so far. The printing settings included 0.2 mm layers, Coex3D green ABS material, and no support structures were necessary.
