Colecovision Super Action Controller holder

In my ongoing quest to organize my classic gaming connection, I have designed a wall mount for another oddball controller from the 80's: The Coleco Super Action Controller!

The Colecovision includes storage for its standard controllers. The "Super Action" controller, however, is just the opposite.

This controller appears to have been designed with the hilt of a Claymore as an inspiration.
There is LITERALLY no way to put it down in any sane orientation. It always looks like it was just thrown aside.

This was designed to require minimal support during printing. The only place that requires support is the "shoulder" between the large top half-circle, and the 2 lower stabilizers, where it connects to the base.
