Skull-Pumpkin with Bobbling Brain

cults3d

This is a bobble-head (bobble-brain) pumpkin-skull toy thingie. This toy use a 3D printed spring that supports the brain and makes it bobble. No supports are required and you can use minimal infill (10% is fine). The brain bobbles best if you print that part with more infill, but it isn't necessary. This was made from a few different things. First is the pumpkin-skull remix model by Adafruit (https://www.printables.com/model/7204-pumpkin-skull-remix) which is a remix of the excellent original model by Jesus Bibian Jr (https://www.myminifactory.com/object/3d-print-pumpkin-skull-2939). The spring mechanism is based on the excellent bobble head collection designed by 3d-printy (https://www.thingiverse.com/thing:5409630). See his collection of bobble-heads for more fun halloween bobblers. The brains are just something I had laying around... Bobble-Head Assembly Tips: The square spring hole in the pumpkin is oversized to aid assembly. Note: For correct orientation, the spring needs to be installed with the flat side of the spring facing forward because the brain only fits on the spring one way (sorry, but you are installing a brain, it can't be too easy). Install the spring into the pumpkin first (crazy glue is recommended). The tool to install the spring in the pumpkin is included here and its use is optional, but handy. Finally install the brain onto the spring. It also has an oversized hole and so glue is also recommended. Enjoy!
