a lewis machine gun 1/10 for WW1 plane or display ( can be scaled as per necessity)
different part easy to print without support and glued together. normal drum for infantry and bigger one for airplane.
printed mine in ABS 0.3 layer automatic with slicer without any pb.
the short version is for air plane the normal for infantry.
from a file found a long time ago i can't remind where ( but creative commons license), modified to be printable
for the one with not enough z course I've uploaded a version of the barrel cut in 3 parts
you may have pb to print the sight , at scale 160% it is only one layer wide !
a bit of sanding and acetone with a brush to solidify the layer adhesion and to smooth the aspect. gluing the part with abs juice
