Super. Einfach und macht was es soll..... Danke.

The gap for the glas is pretty big, so you can fit a rubber pad inside or scale it down a little bit, but still works perfectly! The AMS on top does not move at all. Print with brim for better adhesion (for the older version). (edited)
Printed with CC3D red PETG, 40% infill and .2 layer height. It is great that it has all the mounting hole options.
The slots are too narrow for a standard Rummikub set, which has tiles that are just shy of 4mm thick. The slots are designed for tiles that are ~2mm thick (at the time of this review, there was no information about this and I didn't do my due diligence to check).
