Creality buildplate holder

I received an additional build plate for the new K2 Plus. I have ordered another one. I have designed a holder so that the buildplates can be stored properly.

One with the Creality lettering and one without the lettering. Multicolor printing is still a bit of a problem with the Creality Slicer, so the holder with logo is available as a 3mf file. 

You have to place it diagonally on the printing plate, then it fits. In other words, at a 45° angle.
