This is purely for looks: I've printed this small adapter that fits the FireWire 400 socket on the original Apple iSight Camer, and has a space for ¼" threaded insert on the other end.

I always loved the look of these cameras and I was able to purchase one recently. There's a hacky way to get FireWire 400 working on modern M1 Macs with a bunch of adapters, but I don't miss 640×480 image resolution enough.

I have it mounted to my VESA accessory rail (available on Etsy and as printable here) and I used ¼" brass threaded insert from CNC Kitchen.
