machine gun "spandau" mg08/15 for german WW1 planes

From a creative common licence 3ds max repository heavily modified to be printable.

I need to increase the thickness of the cooling barrel to get it strong enough to be printed . if you still got problem you can print the file "spandau radiateur 2" which have a very thin wall inside to add some strength (you can keep it or use a small dremel tool to remove it after the print).

the scale is 1/4
you may have some difficulties to print the sights
add the small lever after the paint job
