I'm currently 3D printing a holder for a foam bowl so my wife can feed her cats without washing a lot of dishes, and without the cats chasing the foam bowls as they slide around on the floor. I love that it took about five minutes to CAD that part and slice it for 3D printing. I need to get back to 3D printing gun stuff. I did 3D print some 5.56mm sabots so I can hopefully shoot AR-15 bullets at near rifle velocity from my 10mm Glock, but haven't made time to work up a load for the Ten556 project.
honestly was just doing it as a hobby. Didn't think about sharing or selling. Spent total of about a week to get the model together. 9 prototypes. It's still being refined. Wanted to build one and prove to myself that I could. I'm not currently register on thingiverse. Next build is going to be a quad rail! Stay tuned!
