K40 Mirror Shims

thingiverse

I've finally got round to calibrating the mirrors in my K40 laser cutter. Using the mirror alignment guide on k40laser.se, I needed to elevate mirror 2 a bit to get the alignment spot on. I attempted using washers, but that was just too cumbersome for my clumsy fingers, so I created and printed these spacers instead. There's a range of spacers, from 2.0mm to 4.0mm in 0.5mm increments, which I found was plenty enough range for me.
