Parapet Adjustable Clamp for Hanging Christmas Lights
Description
This is a clamp designed to attach to a parapet at the top of a flat roof, so that lights can be strung along the top of the roof without needing to glue onto or drill into the material itself. It features both a forward-back spring to provide strong clamping power, while also including a side-to-side spring so that the two teeth are able to both provide good contact with the brickwork even if not perfectly level. It has both a clip that lights can be snapped into, as well as a safety loop that you can tie a security line into as a backup. I suggest using PETG instead of PLA for better UV resistance. Print with 5 bottom layers and 5 top layers (critical for center pillar spring), and 5 layer wall count (for structural stability everywhere else). Instructions: - Print 2 objects per clamp that you need and remove supports. - "Click" them into one another to create a C-shaped clamp. If you go too far (within the first 5ish teeth), you can twist the clip by the base of the legs to separate the teeth and pull it apart. If you go too far beyond that, a pair of putty knives between the teeth will do the trick. - On the parapet, tighten them together until both teeth touch the masonry, then remove the clamp and push them together one more click. - On the masonry, pull the jaws apart so they they clamp tightly, getting it relatively vertical. - Attach your lights into the bottom clip if possible (better physics to support the load).
