Under desk mounting option for a standard power brick (e.g., included with the Sonnettech Echo 5 Thunderbold 4 hub).

Simple brackets to mount power bricks under the desk (or any other wall). Fits any standard sized 148x57x34mm (LxWxH) power brick (or slightly smaller ones).

I use it to mount the power brick of my Thunderbold 4 hub. Hole size for screws are 4mm. Print two of them sideways (no supports needed). I would suggest PETG or ABS (not PLA) for stability / heat resistance in case the power brick gets hot.
