Extended Barrel 3cm
Integrated the Rail (standard picatinny dimensions)
Raised Rail to be level with priming handle.

This print is LARGE -- overall length is a bit over 315mm.

Because this was remixed from an STL mesh file, the final mesh is quite large with many faces. Sorry for the "messiness" of the file.
Finally, I added a custom raft to the model to aid in printability (without sacrificing the smoothness of the front of the barrel).

With my print settings, it took about 34 hrs to print and consumed about 1/3 of a 1kg spool of black PLA
