Who doesn't want a jiggly plant? Here's a fun Springo cactus that prints in several parts.
The cactus screws onto the planter and holds the dirt in place as well. Use glue or a 3D pen to attach the flower. Optionally, add 1.75mm filament pieces to the blossom to create stamen.
I had success printing at 0.16mm layer height, 4 shells, 9 top and bottom layers (you want the spiral to be solid for maximum strength!)
After printing, carefully separate the layers using a thin tool like your print removal spatula.

Non-Springo versions also included if you don't wan't a Springo for some crazy reason! :P
