UPDATE: Been meaning to fix parts of this print, Everything prints with out supports except the wheels and just snip off the extra plastic. I turned the wheels around to get a nice finish on the front and the head I made it so the lens can be screwed on since I noticed different slicers made it hard for the old lens to fit in. new files are marked and enjoy. The light can be added easily with a blinking led and battery just check your local electronics store or ebay.
What is my purpose!
short video of the blinking light I added, was previously a bike helmet light. https://youtu.be/Np1iKPkuH44
I couldn't find a Model that was in pieces so I made my own.
Fully movable Butter Robot
The acrylic lens was a idea that you could paint the inside then add resin or acrylic just enough to make a clear bubble.
I designed his eye around a lens I had found but had made a copy of it to paint.
All the holes are designed around M3 screws but I don't know the length of all as I had just used what I had in my loose screws jar.
2 versions of the head, one is hollow and a hole to the LED to add a blinking light as well as a possible voice box.
For the wires I recommend just finding some thick wire to cut and fit other wise I will post a printable wire.
The track is held in place with a lip that the wheels catch onto.
