Robotic Anti-Rodent Spider is a print in place, no supports articulated model featuring mid and lower leg latching hinge joints, ball hinge hip joints and latching upper pedipalps hinge joints. The model will freely stand on its legs without collapsing. Also a static .stl version is included.

Included are .stl and .3mf of articulated model and a scalable static .stl version

The idea of the model is of a robotic spider similar to the size of a large real spider which could possibly be programmed for rodent control.

I would recommend using PLA+ as it will be a bit more reliable for the latching joints, however I have tested in regular PLA and it will work; make sure you use best printing practice, dry filament, check temperatures etc.

Gradient filaments look good with this model, as the material layers with the legs have a much higher material volume than the upper body; this results in a faster colour transition across the legs than across the body and abdomen.
