I lost on of mine. Had one of my customers spin one up for me on his lathe (of course, I found the missing one 2 days after I installed the brakes). I'd imagine he still has the program on file. I could get a price on a dozen from him. He's leaving for Aruba tomorrow for a week, so it would be a couple of weeks till any product was in hand*.
*setting up/proofing a small run of parts on a CNC lathe is not cheap.
