This Case has been designed to be a rugged enclosure protecting the Akso from being knocked around on your desk and during transport and gigs. Once you get the backplate on and screw it down the enclosure is very rigid. The built-in feet elevate the Akso slightly to help protect it from surface spills.
More info about the supported board can be found here https://zrna.org/akso
Prints in 2 parts and I recommended it be printed at 0.2mm layer height in the default orientation with supports in the USBC/SD cutout section. All Screws are M2 try to get some with low profile heads.
