LM270WQ1-SDA2 Controller Board Holder

This is the holder I used for my [27-Inch Apple iMac External Monitor video](https://www.youtube.com/watch?v=D6mv1pIf45M)

Some tweaking may be required, I had lost the last version I printed and recovered it from a backup (stored in one of my 3D printer's SDcards). It may be out of date...
