These are great just printed them and aligned my mirrors and they made the process so much easier

I made these, and they are a big help in preventing smoke and residue on the mirrors during calibration of my K40. The slots for the paper were a little tight and I had to use a razor knife to trim them up a bit, but I can chalk that up to my printer tolerances. I would also suggest gluing/taping a piece of aluminum foil to the faces of these so they aren't melted by the laser on a burn through of your targets. If you do this, however, I suggest only firing your laser with the lid closed. The foil will scatter the beam everywhere and could pose a safety risk.

Spot on ! Thanks, saved my mirrors from contamination :)

Just what I was looking for! Printing it now. Thank you.
