Holder for the Olympia Circuits Arno Board
I made this up to give you a little more room to hang on to the Arno. It also covers the back so that is won't scratch things.
I had to scale up a bit in Sketchup to get the right fit with my printer. The .stl creates a snug fit for me. Flex the holder to release the Arno, rather than pulling on soldered parts.
