Need Feedback on Rotatable Snap Fit Joints
January 01, 2016 11:40PM
Hey guys, beginner here so please excuse the errors.

Im trying to make a finger for the purposes of being fully rotatable up and down when 3d printed. I split the finger into 3 solidworks parts. Each part has snap fit joints to allow for rotation. I need some help with getting an opinion on the actual "snap fit" joints I made.

[Pls see the 3d view of all 3 components before continuing in the link provided below]


Basically: Is my snap in semicircular joint design going to be feasable? Will the male part of one finger properly snap into the female part of the finger, and actually allow for my finger to rotate down? I made a 10 mm radius for both the male and female parts. Not sure if the female part should have a slightly larger radius. I don't have access to a 3D printer right now so I was wondering if theoretically this design would work.

It needs to snap in by more than 180 degrees. The way you have it now they will nest together, but they wont snap and stay together.
