These are print in place designs that intentionally use severe overhangs to produce a bushier, more relistic looking Christmas tree. Version R11 offsets even number branch layers to look even bushier.

Do not use supports since the branches are intended to droop.

The rings floating in space are intentional and provide a little bushier appearrance.

The dimensions (mm) of file christmas_tree_2025_R11_251216_large.stl are:
X = 97.31, Y = 97.31, Z = 157.0

The dimensions (mm) of file christmas_tree_2025_R11_251216_small.stl are:
X = 47.31, Y = 47.31, Z = 78.5

The above trees are a more refined follow-on using BlockScad to two experiments I tried in 2011 in the following Things:
