I am in the process of making them. The mold is done!
But i've been having some problems with the material I've been experiminting with, so it is taking me a little longer. I was going to make them out of cast aluminum at first, but figured for the "few" I would probably sell, it wouldn't be cost effective. It's kind of on the back burner right now until I get some time to check out some other materials that I can possibly use that won't be so brittle, and can withstand 150 degrees, and cheap enough to make it cost effective! I need to knock out a few other projects before I get back on this, but hope to have it finished by the end of the year.
