Keeping light-weight material on your Glowforge, or another laser cutter, the cutting bed can be a pain in the ass. So what can be done about it? A lot actually. Some people use small weights. Others use clips that clip into the hex grid of the Glowforge laser cutter. I prefer to use some powerful magnets from old (dead) hard drives. Combine them with a little bit of scrap acrylic and you’ve got a nice custom solution to help you keep your laser material in check.
