Summary

This is a simple robot leg model that uses two cheap servos to simulate a robotic leg that can be used for experiments with kinematics.
I used a pair of basic micro-servos and an Elegoo Nano to drive them.
I have a video of this in action on my YouTube channel.

Post-Printing

Just a little trimming of edges. The stand and base push-fit together with a dab of super-glue.
The upper servo slots into position and is held in place with a pair of self-tapping screws which came with the servo. The L1 link push-fits to the servo horns with a dab of super-glue and the screws from the servo kits.
The Elegoo Nano is hot-glued to the rear of the stand. I cut a strip of PCB stripboard to mount some pins for the servo connectors to plug in, so they can be replaced when they fail.
