insta360 Link backplate for Elgato Prompter

I really appreciated gmorse81's original, but I kept breaking the side clips on the prompter. I also had to re-drill the mounting holes, so I decided a complete overhaul/remix might be more helpful. Here's what I've tweaked: 

1. The backplate no longer clips into an attachment ring; these are now one piece.
2. Bevels added below most of the attachment flange, increasing sturdiness and also requiring less printing support.
3. Mounting holes have been resized and realigned with the prompter body. 
4. Camera cradle now has a “popped collar” that hides the red/green/blue LED indicator light, so that it does not detract from on-screen image. 
5. Camera cradle and backplate now each have an aligned hole on bottom for you to add ¼"-20 screw and thumb nut. This adds a layer of security and makes it so that the camera won't fall out of the cradle if the rig is inverted. Helps with genereal prompter handling and adjustments.
6. Strengthened some other  geometries and moved the cable port.

ABS yields good quality for both pieces. I tried PAHT-CF, which was awesome, but that caused too much friction for the cradle to mate with the backplate. The increased strength (at cost) also seemed overkill, so I reverted back to ABS. The Cradle in my images was printed with a .6mm nozzle but I've been able to get much smoother results with a .4mm nozzle

My next remix will involve making the backplate/box as small as possible…however, the current ‘boxy’ design does enable a simpler print with less support.
