RC generic body posts, 4 different lengths, 8mm diameter (quite large), fairly sturdy. The title sums it up mostly.
92mm, 76mm, 55mm and 45mm, should be generic enough to use anywhere where the body post doesn't have to slot into any predefined socket.
Printing it's best to do it laying down with supports to the build plate and 3 walls at least. You can experiment with infill to see what works for you, I stick to around 25%.
You can also try printing them with the body pin holes vertical or horizontal, one has a better finish to the sides of the body posts.
Also if you choose to print them vertically like the sample image you end up with very narrow layers trying to hole the body on and any little graze of anything tends to break them. Ask me how I know lol.
