Elbow joint (snap in, STL and 123d file)

thingiverse

hey. I made this elbow joint in order to integrate it in other pieces, like figurines or some other parts. It's two 10mm cylinders that are joined by a 90 degree (with one side flat on the male part) or 180 degree joint. Good for elbows and knees for the 90 degree version and for who knows what for the 180 degrees one (the one where the male part is completely rounded). here is a short vid of the 180 joint: https://youtu.be/VCa5kigsRd0 It looks like it didn't go all the way to 180 but my fingers were in the way; it does do the full 180. Anyways, the real important part here, I printed about 10 various iterations of this until I got one to work well; I tried different ball sizes (the balls that stick out and snap in the recesses) and they all broke the sides of the female part until this one. It's probably scalable, I haven't tried it. I'm uploading the 123d file so you can go from there and integrate it into other projets (to open two separate files in the same 123d project, just open one, and then drag the other 123d into the window; it'll ask you to open in current, or create new project.. just open in current....) This was made with PLA (which is less flexible, which is why you need the right tolerances), printed at .2mm with 10% infill any more infill just makes everything tougher, for extra tough action figures, I guess. If you like it, LIKE it. or collect it. or both! if you use it for a project, make certain you post a made it... that'd be awesome.
