Yet another Humbucker Pickup Ring

Humbucker pickup ring.

I left this solid rather than shell it out like the injection molded style.

Shelling isn't needed and this way it will print bottom side down without fill.

The mounting holes work with M3 pan head self tapping screws (that I had already; hence no c'sinks).

There isn't room to c'bore without getting too thin so I recessed the corners at the mounting screws.
