Raspberry Pi 7 Inch Touchscreen Case 2020 Mounts

Remix of Leetspeak's excellent Raspberry Pi Official 7" Touchscreen case mounting arms. Per the original design, you have to assemble the mount by sliding it onto the end of a 2020 or 2040 extrusion. I didn't want to disassemble, so I trimmed the retention tabs so that they act more as clips, this way you can slide the mount into position. The original design is more stable, but far more cumbersome to install. This is less cumbersome and surely "strong enough". Enjoy!
