Summary This laser is very expensive and the battery cover is fragile. I designed a new cover using a 1/4 - 20 screw that is supposed to fit into a tripod bracket. For the metal battery connector, I heated it and forced into plastic so that it glues there. You have to cut off 4 rubber pins, kind of legs I had bad time with the round part of the case, i had to drill a hole and put an other screw... So I modified the design leaving more room for that thing. I also fixed an other problem: the red point is originally 2 3/4 inches from the ground, witch is not a good thing for make calculations. So the case raises the laser to 3 inches.
