UPDATE: 11/19/18, China lied about the diameter of the security camera. I uploaded 2 new files called SC_Faceplate and SC_LensRim that will have an enlarged hole to accommodate the actual diameter of the camera.
Here is my version of Butter Bot! from Rick and Morty. It also can double as a security camera!
In "Something Ricked This Way Comes" upon its creation, it asks Rick, "What is my purpose?", in response, Rick tells it to pass the butter. Moments after completing its task, the Robot repeats, "What is my purpose?" Rick clarifies that it passes butter. It looks down realizing its sole reason for existence is for something so mundane and says "Oh my god." Rick responds "Yeah, welcome to the club, pal."
The arms articulate as well as the head and body. The tank treads do not work. I designed this around a button type wifi security camera. If you want to use it in that way do not print the lens or lens cover files or the BB_Faceplate file. Instead print the SC_Faceplate file and optional SC-LensRim file instead and just pop the camera in place.
The tolerances are very tight on this. Please use an xacto knife and/or file to clean and loosen the joints before assembly. You may want to apply some lubricant as well. The small bumps on the inside of the arm joints are intentional and are important. When assembling they should all be lined up at the top. Once the pieces are assembled, the only way to take the arms apart would be to realign the groove and peg.
Print the arms and joints solid for extra-strength although they will work with about 15% infil if you are careful.
