In a continuation of our quest to 3d print a robot I posted the assembly of the 3d printed planetary we hope to use as a replacement for the toughbox minis. I posted the video at
Its an edit of the assembly of a couple of gearboxes as the camera kept dying. We built 4 at this time to test it in the drive system of an all plastic 3d printed "skateboard (32x28 in) which for testing purposes we intend to load up to full 120 -150 lb (probably will sit a student down on it).
Would there also be interest for me to do some videos as to how design this stuff in inventor. Currently we 3d print htd-5 pulleys, gearboxes, frame pieces etc. Please let me know and yeah - subscribe etc
