Needed a mount for the Belkin Pro Thunderbolt 4 Dock, to install it under the desk.

The dock clicks in place when installed.
The bridge acts as a distance block while installing the sides to the desk, and also acts as a lock, where the dock clips into when installed.
The dock gets quite hot, so I kept some mm distance on top to not cover it up to much.

The 3d print files also includes mounts for the power supply.

Dock mount mounts to the desk with 4pcs 4-4,2mm x 25mm screws (PAN head recommended).
Power supply 4x16mm screws (PAN head recommended).
