I made the ball bearings of the omnidirectional rotation type.
This comes with a ball retainer.
But this assembly process is at all unnecessary.
This feature is that the shaft is capable of omnidirectional rotation relative to the housing.
But rather than such use, I believes this mechanism can be applied to something.
For example, it is the joint of the robot.
Device : Replicator2
Quality : Low / Raft : no / Support : no
Layer Height : 0.3mm / Infill : 10%
Number of Shells : 2
Materal : PLA
By separating the bearing body and the raft, you will be able to rotate lightly the shaft.
retainer and the housing and the ball will be separated by applying a light force.
Then, please remove the small support that is attached to the bottom of the ball.
: Postscript :
However, if you put the support in your technique, please use the "* -no_support .stl" files.
