1/4 20 bolt

thingiverse

This is a 1/4 20 wing bolt and it has .55 inches of threads. I designed it on Fusion 360 and printed it upright out of petg standing on its head. It might be stronger if u printed it on its side but I you would have to do it with supports and make sure the threads were done right. It would probably print fine with pla but i don't know if it would be as strong. I used it on a 39" wing span HOTS II and it held up for 2 landings and then on a not so good hard two bounce landing it broke.
