Saber 2 is a larger format version of my original Saber design (the original Saber design was inspired by the Disney "Cyber Tiger" video attached). At 14 inches (36cm) long and 10" (25.5cm) tall, Saber 2 is 1.3 times the size of the original Saber, and uses a mostly threaded assembly as opposed to the press fit assembly of Saber. With threaded assembly, Saber 2 travels much better between trade show appearances than Saber, and with its increased size, it definitely attracts attention. https://www.youtube.com/watch?v=EE9RNny2LIc https://www.youtube.com/watch?v=KvihnPGn6W8 Saber 2 consists of 108 total components (34 unique), 5mm .08 and 8mm 1.25 threads, and large parts, thus it is a challenge to print and assemble. I've completed 4 of Saber 2, and while it does present quite a challenge, once completed, each one impressed everyone who saw it, including my grandson who roars at it every time he sees it. In order to complete Saber 2, you will need to purchase a 6VDC 60RPM gear motor (described in Step 2) and a power supply (I used a 1.5VDC AC to DC converter). And as usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make mistakes in plenty. Designed using Autodesk Fusion 360, sliced using Cura 2.3.1, and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
