If you get your diode pre-installed into an AixiZ module, then the AixiZ module will fit into my heatsink. You will need a 1.5mm Allen wrench for the heatsink set screw. The set screw will be there, but the wrench is not included...
The only tricky part, is to then thread the entire assembly into the head of the host without letting the heatsink/module assembly turn separate from the pill. Otherwise, the wires will get twisted...
I have found that you can just pinch the heatsink/module assembly together with the pill/driver, and then turn the head of the host with your other hand until it is snug. Then use some needle nosed pliers to put a final tightening onto the pull by putting the tips of the pliers onto the slots of the pill. (or solder blobs if no slots)
You do not want a loose heatsink because then it could twist while focusing your lens... Plus it is better heatsinking when it is tight to the pill and host...
So yes, it is a very easy assembly with a 'Hot' option if you have your diode pressed into an AixiZ module. But you must still have some basic building skills...
The lens just threads into the AixiZ module. If you get the EzFocus adapter, it just threads onto the lens before you install the lens. That part is easy...
