O-rings, of different diameters, *connected* by 3 radials, all as ONE

I'd think a decent machinist could make an aluminum mold for $150 or so,
if you can find some liquid O-ring goo to pour in there. A couple of
flat plates, a ball end mill, an entry level CNC, and you're done. Hell,
you don't even need the CNC if you know how to use a rotary table, but
it takes longer.

MIght need to spend a little time with an X-acto knife to trim the
flashing.


How much does it cost to just replace the filter unit? I'm all for
fixing something but if it comes down to this extreme, and modern
versions are readily available then why?
