Segmented tardigrade

Remix of [Articulated Tardigrade](https://www.thingiverse.com/thing:5376565) by [mi_replica_3d](https://www.thingiverse.com/mi_replica_3d) scaled to 86mm long, with new joints for more reliable printing and split into individual segments for easier reprints and color swaps. All together, this is about 6.5 hours of print time at 50 mm/s, with 15% gyroid infill.

The mouth and feet are now fused into place, but the body segments and leg joints are still movable. The claws have been made taller. Each body segment has a vertical slot to admit the C-shaped knob on the preceding segment. The fit is very tight during insertion.

Do NOT use all-or-nothing slicer supports. Use support painting or geometric support enforcers to add supports under the C-shaped body plugs (on segments A-C and the head) and under the ends of the claws (segments A-C). If you don't know what those are, I recommend checking out SuperSlicer or PrusaSlicer, though newer versions of Cura should support this as
