Shattered Glass Ultra Magnus Matrix Holder

The Shattered Glass Ultra Magnus figure includes parts from the Legacy G2 Laser Optimus Prime, including a red Matrix. However, there isn't a good place to store that piece in robot or vehicle mode. This adapter piece allows the Matrix to be stored in the chest of the inner robot, which you can then see through the red-tinted windshield. It's also still visible through the double window of the larger Ultra Magnus with full armor. The adapter doesn't interfere with the transformation at all.

One note, there isn't a great way to grab the piece once it's inserted to take it back out, so tweezers or something similar are helpful to remove it.

This can be printed without supports or rafts. I used .35mm layer height, .4mm nozzle, since very little of it is visible anywhere once installed.
