Please review these drafts.
Decided to follow standard “star” shape, though mine is rounded to make centering easier if necessary.
I still haven’t heard about optic holes for the 20mm. Should I just leave it blank? So everyone can just drill themselves?
I prefer to leave it blank, since in this CDTP design, anode/cathode surface area is of high importance.
@Barkuti: Dude, you get those slots. 
Thank you,
So the +trace is one large pour over the entire surface with just a clearing for the -pad which is a small connection the size of the solder pad going down to the core?
(I’m not familiar with single led optics so I can’t advice on the holes)
That, I can’t tell you yet
Ever wondering why this budget friendly Sn96,5Ag3,5 with superior thermal conductivity 78 W/M.K is not so popular?
Here’s the answer: http://www.psma.com/ul_files/forums/leadfree/aim_lead_free_guide.pdf
The short answer is it has somewhat troublesome wetting ability. Not a good thing for automated soldering. But for us who really likes to spend hours just to get perfect reflow, this should not be a major problem. The jump from ~50 W/M.K to 78 W/M.K is indeed worth the hassles.

Eye candy
Nice render, time for and avatar picture change?
Ah, Forgot that. Thanks Jos
The PEEK screw and 12 W/M.K thermal pad samples are on their way to my workshop……
Will be a great chrismast gift!

Any updates on the PCBs and screws?
The screw samples are still on holiday trip to my country. Just received the expensive thermal pad samples this afternoon.
12 W/M.K 0,5mm thick, not bad eh?
0.5mm thick copper tracing??
OMD, I wish… 
No, it’s the thermal pads to insulate the MCPCB from the base
Ah, completely mistunderstood it then, or it was wishful thinking 
FYI,the next VirEnce will be 3 oz thick minimum.
I’m an SI person, had to look that up: 3 oz = 0.1mm sounds good
I could not find back what the copper thickness of my 119 boards are, but a common thickness for Kerui seems 0.036mm, that makes your tracing 3 times as thick.
I’m an SI person too. It’s just Oz is a universal unit used in many copper tracing industries. Yes, It was hard to convince them to make 3 oz for me. I had to insist on it (at additional charge). I haven’t place the order yet, even though I made them busy for weeks
They have one of the best customer service in the industry.
Great, thanks!
When will you get samples of the PCBs?
Later when the high season ended I guess. Too many unexpected expenses for now
The samples just arrived
Features:
- Thermal pad: thermal conductivity12 W/M.K; thermal resistance 0,12 C/W; electrically insulator; compressible down to 30% (0,5mm down to 0,15mm)
Datasheet: TG-X
Estimated price
- 21mm x 0,5mm thermal pad: USD 5 - 5,2/pc
- 17mm x 0,5mm thermal pad: USD 3,7 - 3,9/pc
