I made this part because I wanted to add new weapons for a set of custom Micronaut figures I am working on. I have only included one of the "weapons" for now, but the base piece is most important for making your own.
This part was made with Tinkercad. Edit the part online at: https://tinkercad.com/p/acc003b316709c1b
Adding two of these head to head could allow for more functionality, but nothing I needed... yet.
