Hello Laser Community! This is my first post and I'm coming to you with open arms and a desperate need. I've scoured the internet and have had no luck outside of one cap that is too big for my laser. I am looking for a straight line cap for a laser pointer to create a "sheet" effect in a laser show. Does anyone know of any companies that stock such a cap OR a company that will make one for me. It's not needed for a month or two so have a bit of time. Any suggestions are so graciously appreciated!
