This is my 2nd self-designed object and also a Borderlands 3 prop weapon. This is modeled after the Hyper Hydrator 5000. Although I did a better job at separating body (STLs), I still did a fairly bad job designing it so it would be put together well. Weight is off and I don't have pegs to help guide where the parts should go. Also, I had size issue with my trigger so it didn't seem to fit perfectly like you would expect. I included a few STLs for the tiny cord that can connect the two barrels but I didn't add that to my model yet.
With that being said, it was still a fun project and I'm happy with how it came out.
Trigger and tiny cord are not great fits. Parts were glued together with no problem, but there are no pegs that help guide the placement. You'll have to eye ball it but it should hopefully make sense. I tried to make the STL files just "load and print"
