I had a printer jam 9.5 hours into this 10 hour print :P. I measured the result from the bottom to the point of failure and used netfab to slice the model and print a cap that matched the failure point to within about 1mm. I then sanded it to match perfectly. You can still see a very faint line in the final result, but it turned out better than I could have hoped for given the failure. The legs and arms move very nicely and the head rotates freely. What a beautiful design.
