If you don't have a phone that can charge on the console puck charger in a Rivian, or just don't want it drawing power all the time, the puck charger is a waste of space.  It can be removed, as shown in this video.  One could then put a spacer in that space and put the rubber pad back, but I decided to print a tray to fit into the space.

I printed mine using a 0.8mm nozzle and MatterHackers RYNO filament.  Nylon would probably be better but I haven't been able to do that yet.

Version _2 has a slightly wider, flat-on-the-underside, rim, instead of the self-supporting cantilevered rim of the original.
