This is the K-16 Bryar Pistol from Star Wars Battlefront.
I always wanted to model and print a blaster for myself but I wanted it to be different and stand out.
All pieces are pretty easy to assemble. but just in case, I added some exploded views in case you get confused regarding some of the smaller pieces.
The handle and the main body both are split in half and will need to be glued together however I added some pilot holes for nails that you can use as registration pegs.
I also modeled the screws that go on the gun but unless you have an sla printer, it miight be too small to print. I also added pilot holes where they go in case you want to drill it out and add real screws instead.
The last photo might be a bit confusing but basically i hollowed out the handle a little bit and added more pilot holes. You can use the space to modify the trigger to make it actually squeezable. I used an elastic band/screw as well as some hot glue with a pen spring. Both worked. Or you could just glue it down to avoid a hassle.
I also hollowed out the main body in case anyone would want to add any electronics
