Propeller Block revised
thingiverse
A propeller block is used to keep the blade from turning when removing or installing the outboard motor hub nut. Many people use a block of two by four wood, but this device stays in place on its own. A very slick and handy device, this will print out a bit heavier than expected if you use the recommended infill of 60%. Typically, the torque required to seat the hub nut will be in the neighborhood of 50 ft/lbs. If printed vertically, this device will easily do the job without being damaged by a stainless steel propeller blade.
