Omnibot 2000 Arm Joint

myminifactory

Do you have an Omnibot 2000 robot - http://www.robotsandcomputers.com/robots/personal.php?filename=omnibot2k.htm - whose arm hangs limp at its side? The problem is likely a broken arm joint. Look closely at the second and third photos to see where this common failure part breaks. I once glued mine back together long enough to create a silicone mold from which I cast a functional, albeit ugly, replacement years ago. Now that I have a 3D printer, why not use it for something useful? This replacement is identical to the original, with one exception - the top part has more material to aid in strength. In the photos, note that the purple piece is the printed replacement, while the grey piece is the original. This part is impossible to locate, and as far as I know, there are no other sources for either the joint itself or a 3D model. For now, I'm offering this to the public at no cost, but I reserve the right to pull it from the marketplace at any time. You're free to print this for your own use, but selling the file or the finished piece is strictly forbidden. If you find this model helpful, a tip would be greatly appreciated!
