Called Bob Garrish of Saint Luthierie because he didn't reply me when I try to buy from his site, but said he doesn't make the plastic jigs anymore and gave away his last one. Now only makes aluminium and in bulk of 10s for 70usd ea. Said that one could make a usable one, and don't have to buy, "maybe they want nicer looking one...". Very helpful as I asked about materials. He had used garbage bag for membrane and it worked!
He pointed me to Official Luthiers Forum where I can find the Vacuum Jig Plan
