How To Draw 3D Printable Snap Fit Ball Joint
-
How to draw a basic 3D printable snap-fit ball joint in SketchUp. Consumer & hobby grade printer results vary, so this is a little bit tricky with ABS plastic and delamination problems etc. Perhaps Nylon works very well.
If your parts still tend to broke, make a double "C" opening both sides as on the video, making an intersection piece (deformed ball) 0.80 scale instead of 0.9. And even without the opening scaling.
Use your imagination how to continue design of the part.
I have here the undercut / opening calculations formula, but the drawing is just estimated close to it. Perhaps you have to experiment with the shell thickness & infill etc. I had them 0.8-1.2mm and 15%.
The printer was Reprap Prusa i3. Clean the parts well...Still trying fine tune and make better ones ,but this joint has been working already well.
