My wife bought some solar deck lights from Target (Threshold brand that come in a 2 pack) and I didn't really want to screw them into our old fence. I created this and printed two so I could hang the lights from the top of the fence pickets. This could also be used as a temporary mount if you aren't sure how far apart to space them before you attach them with screws.
This was printed in black PETG since these will be outside in the sun.
