Bobble the head of your favorite leader of the heroic Autobots!
I wasn't able to find the source for the head model I used for this bobblehead. I found similar ones, but not this exact one. If you find it, please let me know. All I did was scale it appropriately, and use the template negative volume to cut out the hole. Get the rest of the needed parts (spring and base) from the linked original Bobblehead models, or use my 3MF file or print the provided gcode appropriate for your printer.
Transformers! More than meets the eye!
The author remixed this model.
