Awesome design! I made one and the main body parts felt rock solid and fit together nicely. I don't think I've ever had this much success with a multi-part build before. I'm printing in PLA on a Printrbot. I did have to print the main gears at 103% XY keeping Z at 100% and there was a little bit of filing and oiling. Bit, I am impressed! Great design. Great Video. Thanks for the effort.
