At last, it is finished. The battle rifle from Halo Reach/Guardians (it appeared in both 4 and 5).
I have not bothered orienting the parts for printing, I was fed up with it by this point :).
Overall length is just on 1000mm (40in.).
Supports will be needed for some parts, sorry.
Also, due to being fed up with it by now, the stl files have not been run through netfabb, which I would recommend doing before attempting a print.
