This is for a mini mega tree topper, it will hold up to 12 strands to create a 180 degree tree. When printing increase walls to 4, infill was set to triangle at 35%, speed set to 75. I used PLA but can also be done with PETG with some print setting adjustments I'm sure.

The Topper will fit on to a 3/4 in schedule 40 coupler. That coupler can then fit inside of a 1 1/4 in schedule 40 pvc pipe. Due to the weight of the pixels I would not recommend more than 30 pixels per strip.

8 inch star available as well to go in top.
