The STL are all for the left side of the gun, just mirror them to have both sides and use the pins to join them.
I remixed and cut Industriald's model
...Show more (https://www.thingiverse.com/thing:650045) using tinkercad because I wanted to gift it to a friend who is a big SG-1 fan but I wanted something that could move and have some minor functionality. Also made it a bit shortrt and bulky like the ones on the show.
Also included an ensambled scaled half-gun and support you can print and display. Again just print one and a mirror one and stick them together.
