T Display Project Case design

This project case was designed specifically for one of the ESP32 microprocessor development boards - the Lilygo T-Display. It works perfectly for me, and so I wanted to share.

The basic case design is in two parts - it's effectively a box with a snap-fit lid. The box is turned over so that the 'bottom' becomes the top and allows the display to be seen through a cut-out window.
The outer case dimensions are 100mm x 50mm x 30.5mm. The case thickness is 2mm for each wall so that inner dimensions are 96 x 46 x 26.5mm.

The key feature of this case design is that the T-Display processor board will simply slide in, and remain captive. The board is held in place on one side by the box wall, on the other side by the perfectly spaced supporting wall and finally at the rear by a support bracket with an overlap that tightly grips the board in place. (Once mated with the USB slot and pushed hard against this slot, the board should be pushed firmly down into the overlap at the rear of the board as the last action in fitting the board). You will probably want to solder the in-line pins to the board before installing in the case.

There are many versions of ESP32 development boards on the market - but one of the features that attracted me to this one was the integrated display on board with all display connections already made. This simplifies my breadboard style projects, but for this design I wanted a project case to hold one of my successful designs, hence this solution.

If you would like to 3D print the basic version of this, I have put the print files for the standard design (case, snap-on lid, window for the display and slot for the USB C) on Thingiverse.
Please note that the video shows an enhanced project version of the basic case that includes an integral battery compartment plus extra holes to accommodate a switch, an encoder, a LED, and a couple of SMA connectors - please be aware that none of these extra features are included in the basic Thingiverse 3D print files.

For information - the ESP32 T-Display development board is powerful (contains two microprocessors) and highly versatile (with multiple general purpose GPIO pins, plus on-board WiFi and Bluetooth). It can be programmed using the Arduino IDE and has lots of library code support, making it a great starting place for electronics projects. The board can be put into a deep-sleep mode where it consumes typically 100 micro Amps, meaning that long-term battery operation is a real possibility, particularly for remote sensor operations.
