Great model! Currently printing this in blue nGen and carbonfill.
I've cheated slightly..... I've taken the tri-joint and printed it in two halves 9mm up the body. This gives me a nice flat area to print on and I just glue together afterwards. If anyone wants an stl for this, I didn't redesign it (although meshmixer will do the chop just fine) I just sink the part into the build plate by 9mm, and invert it to do the opposing side.
I'm not sure on screw size yet, but to be honest I may design a new rod with captive nuts and use standard m5 or m4 screws. Or I might just tap the plastic, depends how lazy I'm feeling.
