Made the M2 Browning 50 cal from the files that HAitCH_ made.
Designed my own muzzle and some new parts for mounting the barrel into the body. It is easy to remove it for storage.
Glued a little magnet and a metal plate on the back of the top cover, so it is hold in place when placed in the closed position.
Took 2,5kg of filament and 180 printing hours. But with a reliable and good running printer it doesn't matter.
When the parts was glued together I sanded them. Then primed with solid spray filler, then sanded again and finally adding some black spray paint.
The brown parts are just printet in brown filament.
Downloaded the files from HAitCH_ and then sliced them up to fit my printer.
30% infill on the small parts.
20% infill on the big body parts.
