Summary

Basic collar to mount a LED mounting strips and a Plastic Pumpkin on top of my mega(ish) tree. The .stl that is shaped like a gear is for the top of the PVC pipe the mounting strip is then screwed into it with self tapping gutter screws. The round one screws to the bottom of the tree topper (in my case a Jack o Lantern) and then fits into the one shaped like a gear.
