The Nexcom NDIS B533 is a fanless desktop great for digital signage (its original application), embedded applications needing a small silent system, PFsense and OPNsense routers, Raspberry Pi-like workloads, and so on. However it does not have any way to stand it up vertically owing to its non-flat short edges and finned surface. This support bracket stands it vertically without covering up too many fins, uses little plastic, does not cover any ports, and is a fairly quick print.
Use the included .3mf file if you want to print it in Lightning mode with as little infill as possible, or the STL if you prefer different settings.
The author marked this model as their own original creation.
