Makeblock mScara Laser protection

Cause I think the Makeblock Laser is a bit dangerous, I've made this protection. Even if the protection is mounted, you can change the focus and can control what your doing through a hohle on the side.
No garanties, but for me it's working.

I've also designed a place for a fan, to remove the fumes from the lens (don't know, how good this is working...)

I like the Makeblock produkts a lot, hopefully some one can use and/or improve what I've made
