FDM .stl pack
This file has six parts –
- Gun trunnion
- Gun barrel
- Gun trails ( x 2)
- Gun wheels (x2)
This file needs to be printed on fine (.1mm) setting with supports everywhere.
Remove supports carefully (open the .stl in Print 3D to see what belongs if in doubt)
The gun barrel fits into support nubs of the gun trunnion. The trails fit into rectangular recesses in the gun trunnion part.
This file has the gun itself and the barrel.
I included the pre-supported files; this may not suit you needs; it has the two parts canted at 46 degrees.
