its pretty simple to make. take your maglight and unscrew all the unscrewable things, you should be left with the battery cap(not needed), main tube, head of the flashlight, and the little ring around the top. in the head part, you can remove the vulb, reflector and all that easily, no cutting or anything needed, next take the plasic lens out and bam pipe, just need screens. i use two in mine, one is a fine screen that sits in the threads where the tube screws into the head of the flashlight, and the other it pinched between the little ring at the top, and the head of the flaslight when they are screwed together. put weed in between the screens, by unscreweing the little rin at the top. and light up
