Laser pointer for K40 Chinese CO2 Laser by ThorMJ

Last crawled date: 3 years ago

An adaptation/improvement on http://www.thingiverse.com/thing:53301
for my K40 cheap Chinese laser. This one is modified:
Clears the hinge/lips on my door (mine has a folded metal flange that tried to dislocate the original)
Steps back behind the mirror
Has a positive stop and a setscrew for angle, and has a spot for a ball-point-pen-spring instead of an external spring.
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).
