The trees are based on the trees found on maker world 621664-christmas-tree-with-skirt. Added thicker trunk, rounded base, and light compartments with feed hole. Various ornaments with tabs designed for reuse and so you don't need a hot glue gun to attach them. Like all trees of this type, the tops are fragile and can break off easily. it's a pine tree, so nothing you can really do there unless you print it solid. Easy enough to fix with a hot glue gun, or 3d pen.
