Its a simple holder/clip for the C7 lights you get with Christmas decorations or for night lights. I needed something to a light in to the the Bambu Christmas Cabin so whipped this up. Its perfect for adding to custom decorations or night lights. Their are three screw wholes for a vertical or horizontal mounting and large flat places incase you want to glue it down instead. I used Gloop and just glued mine in place. i also added a pass throw for the wire to come out the back or bottom of the clip to give you as many options on how to place it. If you want a tighter grip i would uses PLA with an LED bulb but if you need more flexibility or want to use a normal inconstant bulb would recommend PETG
