I’ve been working on and off making a thing that fits onto a bottle of fizz, and has a trigger to let you open it (and shoot something!) I made prototypes in the metal workshop and used Fusion360 to design a 3d model.
I put it on Kickstarter and it got a production run funded, I was pleasantly surprised to find enough interest!
Thanks @platinumnqueen22 for the pointers in the metal workshop back in the summer. I owe you one once I get them back from the manufacturers.
