I decreased the length of the legs to reduce stress on the printed parts while allowing the motors to work more reliably.

I see considerable progress!

One more thing that could work is using rubber bands to take away some of that gravity force the servos have to struggle against — so that instead of being under 100% or 0% load, they would be at 50% load all the time.
