K40 mirror alignment tool

Note one of the large prints does not have a hole in the bottom of the laser tube, thingiverse will not let me delete it though so please dont print 3 check first which one has the hole

This is quite long but

PLEASE READ IT ALL ITS FOR YOUR OWN SAFETY ELECTRICITY WILL KILL

Very simple tool, if you have stripped down your K40 or removed the tube this will make it very easy to ensure the mirrors are aligned before popping the tube in.

This is very simple but accurate if you do it properly.

Print both facing down on to the print bed then virtually no support needed, the longer of the two may need support for the small hole to let out the laser wires

Get hold of a standard 12 mm laser which is what we normally use for a red dot, insert that into the longer of the tubes, wires first and ensure those exit by the hole in the side of the tube. Depending on its voltage attach to a supply with a switch, preferably battery as we dont want you to do this with the laser plugged
