Crank Handle for Ultimate Propeller Launcher

My son suggested a crank handle might be easier to use than the original twist handle. It also provides more leverage to launch the propeller further. We tested two different lengths. Both files are included. The long handle provides more power, but is a bit obtrusive. I recommend the short handle. It's a print-in-place design where the handle spins. I used the same print settings Nikorasu suggested for the gearboxes. Just rotate the handle to break it loose. The hole in the top is for oil, but ours haven't needed it.
