Visible laser mount for 40W laser cutter alignment

The problem with aligning the 40W laser cutter is that the beam is invisible and burning the tape smokes up the mirrors. I made this jig to mount to the end of the laser to align the mirrors with a visible laser beam. Just remember to remove the jig before trying to use the laser again ;)
The laser module is a 'duinotech' red laser diode module from an australian electronics store 'jaycar' that fits nicely in the jig and a couple of drops of gluegun glue holds it in nicely.
