A simple Vase mode print. Then just cut the bottom off just above the initial layers. I used Clear PETG for durability and heat resistance.
If you are having fitment issues, just heat up the base with a heat gun or hairdryer and press onto an oversized light or squish down onto a smaller housing.
Fast print in about 10-15min each.
I used a brim to keep bed adhesion. Since you will be cutting of the lowest layers anyways to opening it for the lights.
Looks great on my tree.
