when you print the FDM file use at least 0.1mm layers; with supports from the build plate; it was only a 41 minute print on my Mk3S, so you could even go extra fine at .06mm and it still won’t take long. There are six parts to the FDM; the carriage, the barrel, the gun shield, the two wheels and the small rear trail spade. Please follow the sequence above for assembly. The recess on the underside of the barrel needs to be cleaned of support material. The gun shield is the last bit to be glued on- if you do that before the gun barrel it will be tricky to get the barrel on.
