Modular desk container

I have this annoying gap in-between my desk and wall because of wiring keeping it from being flush against the wall. To solve this, I made a container that is able to be wedged into the gap so it can stop things from falling down but also hold trinkets. It's modular via dove tails, however depending on your printer's tolerances may require some force. I'm not sure if anyone else will find this useful but ta :) I plan to make add ons for this such as a cover.
