Epoxy Gun Conversion

I had a 2:1 epoxy gun for 200 ml cartridge, but I needed an epoxy gun for a 1:1 600 ml cartridge. 3D printing to the rescue! I could have purchased another gun for $60 or $70, but now I have one gun that I can convert to either type. Since my print bed is only 200x200mm, I had to split the model into two pieces and glue them together. The glue is holding just fine. I also included the uncut version for use with a larger 3D printer. The hardest part with reassembly was getting the large spring into place. A pair of needle nose pliers helped with that step.
