K40 Mirror Shroud and Alignment Jig

thingiverse

This is a little mirror shroud to keep dust off the mirrors and to aid in alignment. During alignment, it's very handy to have a perpendicular surface to work with and the added distance prevents your mirrors from getting smoked up from the burning paper. NOTE: For alignment, I use the little round dot stickers (seen the image) you can get in any stationary or office supply section of a store but masking tape, or bits of post-it notes would work fine too.
