Omnibot 2000 Arm Joint

thingiverse

Do you have an Omnibot 2000 robot - http://www.robotsandcomputers.com/robots/omnibot2k.htm - whose arm is just hanging limp at his side? Most likely, the problem lies in a broken arm joint. You can see where this common failure part breaks in the second and third photos. I fixed mine long enough to make a silicone mold from which I then cast a functional 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 added to aid in strength. In the photos, note that the purple piece is the printed replacement and 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. I am offering this to the public at no cost for now, but I reserve the right to pull it from the marketplace at any time. You can print this for your own use, but selling the file or finished piece is strictly forbidden. If you find this model helpful, a tip would be greatly appreciated! Print Settings Printer: Tevo Tarantula Supports: Yes Resolution: 0.3 is fine for function, but 0.1 is better for form Infill: at least 60% for strength Notes: Wall thickness should be set to 0.5mm with 2 walls to account for the top threads. If you can print the model with standard wall thickness and line count up to the flat portion with a reduced thickness beginning there, it'll produce a prettier print. Sliced with Cura, the support material breaks away easily with XY-Distance set to 1mm. Post-Printing The top hole is intentionally smaller than required. Drill and tap to the proper size after printing.
