This is a base I made up for Ian Albinson's desk/wall mount for the ams lite.

I didn't want to drill into my desk so I made up a little base plate. This allows you the ability to still mount it to the wall if needed. The bottom is countersunk to put (4) 3 or 4mm flat head screws in with the nuts on the top side. Printed with 3 walls and 3 top and bottom layers and it seems plenty strong. Also added cabinet bumpers to the bottom so it wouldn't slide around.
