Found the original was too small for my LED ring and the spacing of the segments was off.

Used OpenSCAD to create a new ring suited to the dimensions of mine, removed the segments and then added back to the base. As my ring is solid I needed to make the top ring support into a separate part to be glued on afterwards.

I'm using an ESP32 so flattened the tray out and removed the holes.

Ring Size: 172mm Outer - 163mm inner.
