Default wtb: pcb screw-type ground point

I'm looking for a star shaped through-hole component for a sizeable power supply using screw terminal caps. The pcb I am using for the the supply is not double sided, so I need some way to connect them to the pcb (preferably w/o wires). These are used as a star ground in yamaha amps; see pic atattched: Click the image to open in full size.

I have never seen anything like that, it may well be a custom part. Still, it could be easily made with a piece of copper sheet and a pair of small tin snips.

That stuff used to be standard production but is likely outdated and hard to find.
Taking Al's advice and diy something similar is easier and mucho sturdier, the ones i've seen were shabby tin can stuff that look like remnants of 70s Japanese and old school tube amps.

solder 1mm pins in all of the holes then use those 8 of those ring lugs of similar shape to those used for RCA socket grounds connections.

Make one, using brass or copper sheet, with standard PCB etching techiques. You can then make any shape you want, easily, and it will be flat (unlike trying to use snips). Easiest is to completely mask one side of the metal sheet, and draw your pattern on the other side, then etch with your preferred etchant (Ferric Chloride and Ammonium Persulphate will both work with brass or copper).

I've made all sorts of horribly complicated sheet metal shapes this way (shields, springs, even a solder paste stencil!).

This application isn't exactly critical, so I've decided to use a few of these instead (though not as many as I would like, they're $0.16 each!).
