I designed a simple adapter for my Savonga Monitor Holder to lift my echo show 5 off the desk.You need two M4 Nuts and bolts to clamp everything together (pipe diameter= 35,35mm). The fit of the echo show is pretty loose, maybe you wanna add some hot glue to make it more permanent.

Also you get Version v2 with slide improvements. I still have version v1 so feel free to give me some feedback.
