ESP32-Presense - ESP32-Devkit case with ventilation slots

<p>This is a remix of the case from <a href="https://www.printables.com/de/social/144469-regularfry/about">@regularfry</a>.&nbsp;</p><p>I just added some vents because the ESP32 gets quite warm when running as with the Espresense firmware.</p><p>Here is the description of <a href="https://www.printables.com/de/social/144469-regularfry/about">@regularfry</a>, which is also true for me:</p><p>I'm using these esp32-devkit boards as ESPresense sensors.</p><p>I just wanted a box I could put them in so I didn't have bare electronics around the house, and I couldn't be bothered ordering some without header pins. &nbsp;At the moment I'm just taping them to the back of old phone chargers and plugging them into the mains.</p><p>The box lets you get at the USB port (obviously, for power) but you need to take the lid off to get to the reset button. &nbsp;Some chargers have plugs that are slim enough to do this but others don't. &nbsp;I've not yet had a problem which needed me to fix that.</p><p>To pre-empt commentary: yes, these cases have no ventilation. &nbsp;In my use case they get slightly warm to the touch, but nowhere near hot enough for me to worry about the plastic or the electronics. ESPresense barely makes them break a sweat.</p><p>These cases are a tight enough fit for the boards that they don't need any fixtures. &nbsp;The slide-fit lid keeps things in place.</p>
