Yeah fits perfectly.  But I knew it would after seeing all your pics.  Really nice colored instruction sheet too.  The nicest instruction sheet of anything I've bought recently lol.  The set screw is nice, because I would probably have used thermal epoxy if not, and would never have been able to get it out.   Now I can just use thermal compound. Like I said, I already killed a diode from heat.  Running a little over 300mA, left on a little too long and the little hair wires connecting to the actual chip melted off the chip. Dont' want that to happen again.  Thanks again!

Good news Steve. Yeah, the only reason that it wouldn't fit perfectly, is if there may be some slight differences in the MXDL batches or something. Good idea with just a little thermal compound. Thanks for the compliment on the instruction sheet! Here's a link to the .doc file if anybody wants to take a look at some install details and notes on fitting the DDL driver:

Hey Jay, I got a question. When you used to make the heatsinks without the screw and you had to press the module in with a vice, how wide did you make the hole so that the aixiz modules had a tight fit?

I used a 29/64 drill bit, which is a tad smaller in diameter than the AixiZ modules. Then, you have to use emery cloth wrapped around something like a phillips screwdriver to sand the I.D. while it is turning in the lathe. The set screw is the way to go! Easy install. Also, easy to replace the diode!

Re: ***MXDL Custom Machined Heatsinks***

Jay, could you post the dimensions of your heatsinks?
it looks like there are a couple of lengths, and 2 or 3 outside diameters there that would describe them.

I may be interested in one or two, think they might fit in a body I already have.

Thanks!

Edit: Picture showing heatsink dimensions removed.

A couple of people have copied some of my stuff not for personal builds, but to sell right alongside me. So I have decided not to share measurements for my stuff anymore. It's a sad thing, but the bad people mess it up for the good people...

Re: ***MXDL Custom Machined Heatsinks***

:'( rats... just checked - mine is just a tad smaller. What I'd need is diameters <25mm , 26.5 mm, 22mm, same lengths.
Guess I'll have to punt...
