For anyone that needs the drawing for a 55g servo, here we go. It’s been some time since I’ve updated but never fear, more boring stuff is to be posted soon 
heres is a link to the actual PDF if you want it! servo body.pdf
If anyone needs dimensions or drawings of the horns, I’ve got the 4 lobed horn drawn and the round one. I can’t guarantee that these drawings have no mistakes, i just quickly draw them. Hopefully they’re of use to some one though.
