Many engineering jigs and fixtures require joints or moving parts.This ball and socket represents one such joint that works significantly better with Tough PLA.
Print this model with default settings for each PLA and Tough PLA. Attempt to mount the ball into the socket. The PLA will consistently fail and the Tough PLA will elastically deform and snap fit around the ball. Furthermore, Tough PLA is lubricious meaning there is less friction between moving surfaces for a smoother application
This demonstrates elastic deformation and lubricity.
This design is a remix of "Ball and Socket (Slotted) Joint" posted by "FunbieStudios" on April 6, 2013.
Print in Tough PLA and PLA respectively.
