Warhammer 40k Bolt Gun for smaller printers

I've cut scienepotato's boltgun up for printing on smaller printers.

"BolterTop" and "bolterbottom" are from printing this in two parts. This prints on my Anet A8 at 90%.

The files starting "4PieceBolter" are for printing in four pieces, naturally. I can print these at full size. Note that "4PieceBolterPt4Flipped.stl" needs to be flipped so that it is lying flat on the print bed.
