I was struggling to find a USB holder that worked as well as the one I had been using on my desk, so I decided why not just modify and use what I like :)
The author remixed this model.
Exactly the same holder, but with 2 hex “plugs” added to the back to mount to a honeycomb wall. There is a rotated hex and normal hex version, make sure you choose the right one for you honeycomb wall orientation!
