CL4P-TP - Single extruder multi-color claptrap with articulating eye and arms

A single-extruder multi-color claptrap! Arms and eye are in articulating sockets, elbows bend, too. Base needs supports to print--good luck, I didn't have time to optimize. I also did not include an antenna (yet), you may want to use a paperclip or similar. Included just the wheel/chassis without the base in case you want to make a custom base or print without one.

All pieces snap or press-fit together, no glue required.

For the multi-color layers, print layers in order, do not move or remove from platen when changing colors! After each layer, simply swap out your filament and print the next layer. I included registration marks at the corners so that slicers like Cura will automagically align the layers. Do NOT include support in these layers.
1 - Black (note: tell slicer to print thin walls for this layer)
2 - White
3 - Yellow
4 - Gray

Make sure you have good adhesion (glue stick worked) and DO NOT use skirts or brims for the multi-color parts.
Print multi-color at 0.1mm vertical resolution, 0.2mm for first layer. Designed for 0.4mm nozzle.

I may tweak/improve in the future. I may not.

Happy BL3 day, y'all!
