I have been having a devil of a time trying to design and build an animated head for my animated crab chassis. My CAD software refused to make stl files of some of the parts, my slicer refused to properly slice some of the parts into a 3D print file, my big printer couldn't get a bad roll of PLA to print properly - it just wouldn't stick to itself. I printed off 14 parts successfully with white PLA but the big orange prints just kept failing.

With Halloween fast approaching, I decided to change to a different design....

Here is a recap of the crab chassis build:

 

And here is the new animated head ....

 

Now I don't need to carve a new pumpkin for it every year.
