This is specifically for the Gorilla Dual Temp Mini Hot Glue Gun. I don't think it will fit any other hot glue gun. It snaps onto the base of the hot glue gun and makes it Gridfinity-compatible.
With strong enough magnets, it can stand upright even without using the built-in legs. Hell, it's so light you can probably place it on a wall or ceiling.
If you don't use magnets, you'll need a Gridfinity adapter to place under where the built-in legs pull out.
