UPDATE: I've put a few of these on Etsy https://www.etsy.com/listing/943346116/vesa-adapter-for-aluminium-apple-cinema

This is a remix of Lazerlord's 30" Cinema Display adapter for 20" and 23" models.

GoPro mount (remix of https://www.tinkercad.com/things/bIA2G1cEBEx-gopro-mount ) is for future accessories like a webcam or lighting.

It's probably overkill but I used M5 nuts and outside VESA holes (100x100 one).

Print instructions

I printed the central part first to fine-tune the printer settings. I still ended up with an extremely tight fit.

Eventually, I printed it with:

• transparent PLA to see eventual cracks
• 1.4mm wall
• 0.2mm layer
• 20% infill

Post makes and likes when you print this! :)
