Really awesome print of a really awesome robot! I initially tried 75% scale*; however there was a problem with the body joint cups for the arms breaking (too little material holding the pivot ball at that scale). I eventually printed 100% scale and while the joint cups seemed still a bit fragile, I made sure to sand down the ball joints in the arms so that the cups wouldn't break. If you use ABS, it should be much stronger I would guess. Make sure the parts are properly rotated before printing. A file listed the wrong color and another noted "x2" when it should be one, but that should be fixed soon. Takes a while to print all the parts, but it's really well worth it. Highly recommended! *UPDATE: 75% scale finished. I used the one-piece body and sanded down the ball joints on the arms. Very cute! Note that bottom of head comes out rough...I may sand it down one day, but bottom is a low priority right now since it isn't visible most of the time.
