On some of my other kits, like the Pocket Mini, 18650, and others, the EzFocus adapters are quite versatile using different lenses. Because you can move the module position inside the heatsink to adjust the position of the EzFocus adapter in relation to the front of your host at focus...
However, the Micro Chrome, as well as the SS 10440 builds, do not have the luxury of being able to move the module around much. Especially since the module must be glued to the sleeve using some thermal adhesive.
So with that in mind, I would say that I would need to take measurements on the completed build, in order to make sure that the EzFocus adapter will sit in the correct position with a different lens...
The other thing is, I did my measurements using a 'flush pressed' diode. If you press your diode past the flush point on a build that has no adjustment in module position. The EzFocus adapter will be out the front just a little more than if it was a flush pressed diode.
I have to make my measurements from a 'flush pressed' diode. Because there are many who press their diodes 'flush'. And they may not be able to get focus if I went off of a fully pressed in diode...
For the SS 10440, if you are not going to be using my 405-G-1 glass lens, and want a perfect fitting EzFocus adapter, I would recommend sending me your completed build so I can get it fit perfectly...
but focusing without your EzFA would be fingertip torture
