An adaptation/improvement on http://www.thingiverse.com/thing:53301
for my K40 cheap Chinese laser. This one is modified:
Like the other one, when you close the door, this lifts out of the way of the burning beam. Remember to hold it up if you're testing with the door open (you can see that I put binder clip on it if I'm aligning the mirrors)! I've also added (not pictured) an aluminum plate to protect the laser diode from the BFLaser in case I fire it without moving the arm out of the way.
Oh, you want to download, separate, and print the "NoCase" file -- the "Case" file has a lot of blocks that I used to design it (eg a block for where the lid contacts the arm, a block for the plane the laser should be at, and a "keepout" area where the arm has to make a bend to not hit the mirror when it homes).
