The Hypocycloid Christmas Tree is formed by sweeping out 5-hypocycloids inside of a 6-hypocycloid, as their size tapers to zero. The two versions use 2 or 3 5-hypocycloids respectively.

This design uses the pattern of the Hypocycloid Vase, but tapers to zero instead of staying constant.

Vase mode is recommended. Can be lit with a tea light when printed in vase mode with no bottom.

See my other Christmas models.
