It took a month, but Shapeways finally delivered my 3D printed parts. There were delays due to both Texas being an ice cube for a week, and Shapeways using the slowest postal method known to man.

I had to grind away a bit of metal on two of the internal plates, but everything otherwise fit perfectly.
The sides have to be pretty tight to get the heavy lever arm to not fall on its own, but it does work. The unit doesn't tip over either, but if I were to use it on a game system I would use the magnets or bolt it down anyways.

I plan on dying all the nylon parts black, and then facing the outside with aluminum tape and polishing that to get a real metal finish.
That won't happen for a bit, as I have Jedi Training Remote Stands to build up and ship out.
