Any thoughts on these three D printed prop nuts?  The prop nuts for these small OMC motors are getting hard to find.  When you do find one they are bucobucks!  My son made these on his three D printer.  I drilled a hole through the thing for a cotter pin, that should hold it on.  Gonna try it!

get’em wet…..don’t let’em set!

Hi Dale,  I can’t tell if the Cotter pin is offset to ride in the snap groove of the prop shaft or if it is centered and required a hole to be drilled.  I’m assuming it is off-centered so the Cotter pin is innthe groove.  That’s not a bad idea.  Mine are printed out of TPU and snap on like the originals. The do have a flat on the trailing end, though, allowing me to keep the detail of the snap feature without filling that cavity woth supports to print them.
