2mm rods I believe are for the landing gear or is that what you are referring to or is it to re-enforce the fuselage ?Good day,
I printed the fuselage and there is no way I can get a 2mm diameter rod in the tubes. The print went great, I used 1 wall with a .4mm nozzle as instructed. The tubes looks fine, but they are basically 2mm themselves.
I'm going to use what ever diameter fits, but I'd like to know what I did wrong.
