Shell for Waveshare ESP32-S3 5in Touch Display

This is a simple shell for your Waveshare ESP32-S3 5in Touch display that exposes all ports (USB, LEDs, buttons, switch, and MicroSD card), including the 16-position screw terminal on the bottom.  It even features a “safe zone” to make it easy to see the maximum size and placement of an internal LiPo battery.

Note: this is only for the “With Touch” variant, as the “Without Touch” does not have the glass lens that this shell is designed to accommodate.  Although, the “Without Touch” variant would technically fit, as the mounting studs on the back would still match up, there would be a gap around the LCD and an “unfinished” look (but that might be better than nothing!).

While this is perfectly usable as-is, I consider it a work-in-progress, as there are a number of features that I would like to implement before it is complete:

1. Icons above LEDs and labels above buttons are very small and don't print perfectly, even on high-resolution printers with small nozzles and minimal layer heights.  It's difficult to find a balance between legibility and size (the spacing between these features is very tight).
    
2. Even with openings over the buttons, you still need a small tool to press them (which makes it tough to enter DFU mode).  Solution: make captive extension pins that are installed into the holes.
    
3. As with the buttons in #2, the battery switch is only accessible with a small tool.  Solution: create a captive slide that mates to the switch lever and is exposed by a slot in the shell.
    
4. The openings over the LEDs could be improved by creating “light pipes” similar to the button extensions in #2, but which would be printed in clear or translucent material (such as polycarbonate) and snap into the holes.

Additional components needed for assembly:

1. 4x M2.5x6mm button head screws (like these)
2. 4x 6mm rubber feet/bumpers (optional; like these)
