This is a cradle to securely hold the Vectrex controller in place on the Asteroids control panel. Before this, there really wasn't a place for it. You had to hold it in place, and it kept getting pulled down by the weight of the cable. Since MASTEROIDS supports Vectrex games, now you can play them and not worry about dealing with the controller. The button holes are wide enough to give a little room for slight variations of button distance.

Tested with Asteroids Deluxe full size and cabaret Asteroids control panels. I would be surprised if it did not fit Asteroids full size or cabaret Asteroids Deluxe. I see no reason why you would want this with a cocktail cabinet, since you could just set the Vectrex controller on top of the glass. But if somebody wants to try it, I would be interested to know how it worked out.

This WILL print on a Prusa Mini. You just have to turn it diagonally. You should also add supports for the side holes. That's really only where they are needed. See pic for example.

Note: You will want to buy an extension cable to use with the controller.
