I made this 3D-printed Einstein bust, with a secret switch, that you can use to, for instance unveil you batcave, or just as a fun decoration. Check out the Instructable I made, here: https://www.instructables.com/id/Einstein-Bust-With-Secret-Switch/ , to learn how to assemble it.
I remixed the Einstein Bust by lloyd chidgzey (LSMiniatures).
But everything else I designed myself, in Fusion 360.
I hope you like this, and if you do, I would very much appreciate if you voted for me in the BigandSmall-contest on Instructables, and feel free to follow me on Instagram and Twitter (@Anders644PI) to keep updated with what I make.
NOTICE: The Einstein Head and the Bottom will have to print with support.
