Been a while since I've made a mid that required an actual tool. A while back I ordered several of part number 85037 from eReplacementParts.com. One for each mini pot and one for the new WSM. Installed the ones in the mini today. Wish these had been around years ago. In order to install these you will need a 1 1/4" drill bit, I used a hole saw. Started in side then came in from the other to finish the cut. Had a small burr to sand/file (couldn't get to my file, garage needs a spring cleaning!). Smoke away!!!
