Get your bling on for the biggest human show on earth.
Feel free to copy and update on your own (Fusion 360 link), and experience the horror of my design skillz.
I printed mine on SLA with tough resin, but I expect it'll print nicely face down on FDM. Personally I'd use PETG or ABS but do what ya like.
EDIT 20180813: Replaced all models with updated ones including: ring size on bottom side of Jack, rings positioned properly for optimal printing without having to reorient.
