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.
This stacker allows you to place Nexcom B533 units on top of one another to save space. Normally the B533 cannot be stacked owing to its slightly convex top. However, by placing these stackers into the short ridges, you can stack them.
Print two, one for each side, and place them into the crosswise fin ridges with the “feet” pointing toward the center, not “down.” Make as many as you need to stack your Nexcom units.
The author marked this model as their own original creation.
