Not that I know of but I’d love one too.
Keep in mind the T2/T3 has a weird little raised edge around the perimeter of the shelf. The stock MCPCB is shaped to accommodate it. For a new MCPCB, you’ll either need to remove some material from the board (if there’s room), mill away the lip on the shelf, or use a spacer to raise the board above the lip.
Lastly, you may have height issues when you replace the reflector with a triple/optic.
Here’s a T3 triple I made with a TS10 board (which I had converted to a single) and the TS10 bezel.
Oh, one more thing. I’m working on a replacement head mod for the T2/3. I have some brass plumbing fittings that will work perfectly. After some shaping they won’t look like hardware. They’ll allow for an 18mm board which is within reason to file down from a 20mm board. I’ve finally started the project and will make an ongoing post about it soon and link to it from here.
