Iron Man Arc Reactor Mk2 - Proof That Tony Stark Has a Heart Ring

I printed the Arc Reactor and the Arc Reactor stand from the links below.
It needed the 'Proof That Tony Stark Has A Heart' ring around it. This is the ring.
It just slots over and kind of wedges on.

This download is for the ring around the arc only. Other links below.

I printed the 1st section in black, then changed the filament to Grey/Silver @ 2.15mm. May vary with your settings.
