kbricks rubber gun

The **kbricks rubber gun** consists of 16 bricks and some 40 connectors and pegs of the [kbricks construction system](https://www.thingiverse.com/thing:3574234). This [video](https://youtu.be/jxEc-kjTads) shows how to assemble the model and how to mount the rubber rings.

I actually don't like weapons but I have no objections agains NERF and rubber guns. This model is supposed to demonstrate that you cannot only build cars from kbricks parts.
