As I've seen some people asking if somebody could build something with this part that is included with the Printer when ordering a AMS Combo, I've designed this part to be a plate holder. It's explains itself pretty easy, you print it, you attach or click it in, and good to go.
Could be that the whole Part is a bit wobbly in the back end, if you only insert one plate. I hope to have a better stance in version 2.

This is version 1.0, I'll add some tray's to the front in version 2.0 but that thing is still in the oven ;)

Also the picture was the first print that I already corrected in multiple parts.
The file you're about to download, is already the newest version.
