Chopstick Gun Holder

I remixed this to mostly account for some usage issues for by BIL that has a spinal cord injury and has limited use of his hand. I increased the size of the trigger, decreased the spring tension for a lighter pull force, and changed the threads on the nuts to make engagement a bit easier. The larger trigger also limits the closure so the chopsticks have less tendency to over rotate and drop stuff.

But since my printer is not very well tuned for print in place assemblies, I also increased some of the sliding clearances so the prints did not come out all fused together and I reduced some of the gear complexity to improve/smooth out printing (less jiggly motions).
