7 inch Touchscreen Case with different mounting options

This is my take on a Case for a 7-inch Touchscreen. The Following Screens will fit:
- Waveshare 7-inch C LCD (1024x600)
- Waveshare 7-inch B LCD (800x480)

You will also need:
- 5mm M3 Threaded inserts: https://www.banggood.com/100Pcs-M3-x-6mm-Brass-Knurled-Nuts-Insert-Female-Thread-Round-Insert-Embedded-Nuts-p-1184384.html?p=Y726071399255201503B
- M3x15 Screws
- M3x10 Screws
- M5 Screws if you want to mount it to Aluminum Extrusion
