Christmas light Spiral tree topper prototype

thingiverse

Create eight leg brackets and attach them with 1/4" screws and nylock nuts, ensuring they are approximately two inches long. The original design employs a three-inch PVC center pole and utilizes 3/4 inch PVC for the legs, forming an octagonal shape for the tree. Next, using center braces and an octagon at the bottom, form a sturdy structure. Attach strings in a spiral fashion to the legs but not the bracing, making them removable when storing the unit. A prototype was printed with PLA to verify that all components fit correctly. It's possible you'll need to sand the inside where the PVC goes to ensure a snug fit between the three-inch and 3/4 inch PVC. For a functional piece, consider using PETG, which will provide better weather resistance and some flexibility. The fusion 360 archive file has been uploaded, allowing users to customize parameters if they want to adjust the size of the PVC support to something slightly smaller.
