This is a NUC desk mount I created for my NUC12WSHi7.
It's suitable for standard High NUCs (with dimensions: 117 × 112 × 54 mm).

Made for easy removal of the NUC if needed.
There’s a cutout for the NUC’s rubber feet to ensure a stable fit.
The mount can be easily attached to your desk using small screws (see photo).

UPDATE: I've added a mount for the default power brick for this NUC.
