Raspberry PI 7 Inch Screen Project Box (or a Thermostat for me)

thingiverse

I've searched for a solution like this multiple times. What I have is a Raspberry PI 3 with several "HAT"s and the official 7" screen that will become my thermostat and household controller. I needed the box to be deep enough to hold all the HATs (50mm) to securely hold the screen and have appropriate holes. This box prints well without support. The two holes on the long end are triangle-shaped for this purpose. There is one big bridge where the DHT22 sensor goes. Printing the side vents can be tricky if they tend to bend up, but I cut down the number of them and shortened their run to make them print better. The "front bezel" piece fits my display with less than 1 mm of clearance. The underlying box has four "pips" that push into the screw mounts on the back of the display. The difference in centers of these pips are parameters in the scad files. The front bezel piece has tabs that fit into recesses on the box to hold everything tight... with about 1mm of play. On the back of the piece is a large circular hole to pass through wires from the thermostat. There are also two slotted screw holes appropriate for the screws that hold my thermostat to the wall. All these things are parameters, although I'm not the best at naming variables in this code. -=-=-=-=-=-=-=-=-=-=-=-= Update: 2019-08-22 After finalizing my design, I needed two major modifications to the v12 box. Firstly, I added a hole into which a barrel plug with o.d. 7mm will screw in. Secondly, I needed 80mm of depth for the 3 HATs (power hat, relay hat, motor control hat) + Rpi4 + screen electronics --> 5 circuit boards. Now, I could have gotten much more creative in how this all stacked... moved the boards around to custom locations and whatnot, but this seemed like the better solution. In addition to the 30 mm of extra depth, I changed the angle of the vents and made them longer to match the increase in size of the new box.
