Transformers animated Blitzwing Cannons

designed for replacements of animated blitzwing, I had designed a peg, however the size is off, so I'd recommend just cutting it off and using something like a M3 flush bolt to screw through the original port and hold the part on, and it makes for a much more solid feeling over just being pegged in, also due to the nature of the part, I'd recommend upping the infill just to make sure they're strong enough for the long run (I used 25%), also if you are wanting to do multicolour, flipping the parts to be muzzle down means your purge block can be minimised.
