Long ago I purchased the welded metal mount from @jasonbar (pics above), but I have a regular (angled down slightly) metal control panel, and the mount is pretty much flat so the yoke would not sit up at an angle. I didn't take this into consideration when purchasing that.
It would be fairly easy to make a simple 3d printable wedge-shape if you can make a cardboard prototype for clarity regarding shape, size, connection points/methods, etc.
- With a few pictures and the desired angles and measurements, I can make a custom printable model for you.

I've been searching online and have found a few 3d printed things, but they are for the GRS which does not have the protruding gears etc like the original/Alan-1. I just need something wedge shaped that would angle the mount I already have back 45 degrees or so.
Just looking for ideas on what I could use... or an altogether different idea is OK too. I'm not married to the metal mount I have.
If you're looking for more of a standalone controller and are good at woodworking, you might be able to make something like this.

definitely needs supports added because the yoke weighs about 8 pounds, plus all the other stresses added by vigorous gameplay.
- Not sure if the yoke's center of gravity and leverage will cause the housing to tip over too easily. Worst case scenario, use the four foot screw holes to attach the housing to a board that extends behind the housing and clamp the back of the board to a stable surface or put a weight on it.
- The holes on the back are for a Neutrik USB feedthru.
- The square button holes on the front are for mechanical keyboard switches.
- The OpenSCAD code for the housing is designed so it is fairly easy to customize it with round button holes, embossed art/text labels, etc.
