The 12mm board is just a fluffed up version of the 10mm one, so it can be ground down to whatever size you need, down to the 10mm original size.
I know, and making and uploading a 11mm version if many flashlights use that size is still a good idea :-)
Well, yeah, there is that, I guess! 
For anyone else I'd say no, but for you--I'll do it. 
It is already done, but Oshpark's system is having trouble again. I'll try uploading again later.
Like Dale said, I'd go with the PSMN2R4-30MLDX.
djozz, are you sure about the Ultrafire LZZ-06 driver being 11mm, my Jexree Mini that i thought was as far as the body & head goes (they have only different reflectors) would be the exact same light is a 11,6mm driver.
I looked up this FET on Ebay and found no sellers that sell them for less than 3 dollars a piece plus $4.50 shipping :-(
To search Ebay succesfully I -unfortunately- was forced to look into all those different FET-packages :tired: . In the end I found this graphic somewhere in a NXP pdf. Perhaps this saves some other folks a bit of what I have gone through:
Thanks for a 11mm version :-)
I would have to take another look at it when I'm home.
Ok, found it. I looked into an old thread of mine: https://budgetlightforum.com/t/-/25476 and the driver of the LZZ-06 is even 13mm (press-fit), I got it all wrong, I remembered that the driver that I used was a mm too narrow, but it was a 12mm board that I used, not 10. Sorry Richard for doing the work, I promise that will keep looking out for a 11mm driver flashlight to build this 11m board in 
.
Ok, that is interesting, that means they are more different than i thought.
The only difference i thought was the that the LZZ-06 had a OP reflector & the Jexree Mini had a SMO one.
I ordered the 12. (They charge by board area, and free shipping! Wow)
Now how do I order the FET. I assume I can get the rest off a Nanjg.
No, this uses the smaller version of the attiny13. Also the resistors and caps are 0603, some Nanjg drivers use 0805.
Oh yes, the smaller version was already mentioned. Thanks.
djozz, I spoke with Mouser today and was told they have offices in Munich and the UK, so you should be able to order the FET from Mouser there in Europe and not acquire the big shipping charges. As I recall, this should be just under a dollar apiece. Providing EU Mouser has them, of course. Digikey should be similar.
eu.mouser.com has them for .83Euro? Mouser-onderdeelnr.771-PSMN2R4-30MLDX
OK, so 13mm instead of 11mm? If we're going all the way up to 13mm, then I might space things out a little bit more so it's a little easier to assemble.
If you are expanding it to 13mm, do you think it would be possible to fit the 7135 on there also?
I have been studying wights 15mm driver single sided FET+7135 that is sandable to 14mm, he used the SSU of course, and if you use the LFPAK33+0603 smd components+ the attiny13a-mmu i hope it could fit 
The light i would like to use it in, is of course the Jexree Mini, for that it would have to be sandable to 12mm, and it would fit djozz Ultrafire LZZ-06 also.
Sorry djozz, i was wrong about the 11,6mm driver in the Jexree Mini, i must have mis calibrated my caliper, it is a 12mm driver.
One very nice thing about this MTN-12DD is that if & when RMM starts to sell these single sided 12mm fet drivers, those plus an XP-L on an 10mm sinkpad is a total drop in 
for the very nice 10440 host the 5$ Jexree Mini :bigsmile: Can you say ~1000 lumens at start from some very affordable parts
Richard you really should considering selling that combo as a quick and relatively easy modded light in your store, there are not many 10440 hosts that can take a DD driven XP-L but this one can, and i bet you can sell a bundle of them and with a sane shortish turbo timer they should be quite safe even.
I think that what would be more feasible on a 12mm would be pads where you could air wire a 7135 if desired instead of having it mount on the actual board. There isn't room for it on the board.
Ok, good to know and thanks for checking out if it worked
But pads is almost as good :bigsmile: there is more room to add height than building up the spring side with components, because with something like with wightâs fet+7135 12mm driver it leaves less than 1mm in the tube with the spring fully compressed.
If you can do a 12mm or 13mm sandable to 12mm with pads for airwireing the 7135, please do
As far as i understand, if we donât install the 7135 it should work just like the MTN-12DD.
Exactly. I never liked having any components or having to jumper over stuff on the battery side. I also didn't like the compromise of the attiny10/PIC versions, but the LFPAK33+attiny13a-MMU are an awesome combination for a tiny driver like this.
Yeah i agree, i felt slightly uneasy about components sticking down in the tube & out from the exposed driver when they would change battery, my plan from early on was to find a tiny light i could mod to very bright, & do it so safe i could gift it to family members and not worry they short something on exposed components for example.
And a single sided driver makes it much more foolproof and it will look stock, before you turn it on that is
I will still probably build one Jexree Mini version with a attiny13a-ssu, just so i can more easy test various firmware set ups to see what i really like in a twisty with that much power.
