Lazor Blades
Description
Instructions
They have only been cut out of 1/8" MDF so far, so if you use another material, please leave feedback for others on what you experience.
Since the piece fits about half-way up on the actual razor blade, it DOES get marred by the laser beam, but by the time the beam hits the Lazor Blade, the beam is unfocused enough to not cut through it (well, at least on my 40W laser). I personally see these as a consumable, since they can be reproduced quickly and easily.

Made a derivative of these and posted it here on thingiverse. See http://www.thingiverse.com/thi... yea they may make you nervous and you may not want to use them in a production environment where you have not so bright people running the laser but if its your machine and you control the environment and you don't have kids to worry about I highly recommend these little guys. They make a huge difference. Not only can you see your work much more clearly but you don't have the edge of the honeycomb table to deal with either. Once you use them you wont want to go back to using the honeycomb table.
Tried these at my lab and they made _everyone_ nervous as hell. I believe the smirk on the face of this thing is basically a "lol, if you're stupid enough to actually make these, you deserve what's coming to you"

I tried using these cut from 1/8" acrylic, and the arms snapped off while trying to seat the blades. :-\ I tried several times... it's just not flexible enough. Hardboard/MDF is probably the best material.
