Building off of mitchese's "PBC Linear SIMO mount for 2060 Aluminum Profiles" model, I modified it by adding wings around three sides of the model so that you can screw the bracket to the top of one of these HOTAS mount systems, in the place of the foam-backed plate that would normally rest on top of the desk. Then, by removing the tension lever, one can simply screw the bracket to the underside of one's desk for a more permanent mounting system. I will try to add pictures of how this is intended to be mounted at some point.
