This is a kit-bash of a Mac Daddy with a DB9 Smoothed Sten magazine well and trigger guard. I did it in Tinkercad, so I don't have step files, just stl. Im not an expert by any means, peruse at your own risk. the real credit goes to the @as.morgan:2 and DB Firearms for their amazing designs. I printed it from Sun PLA+ with 8 walls and 100% infill; and full supports.
