Help Designing a bearing housing

Hello,

Im trying to design a differential joint and I need to connect a bevel gear to a frame using a short shaft and a 608zz bearing.
I know I have a shrinkage of 5%-10% in the part after its printed, but my questions are more concerning the initial design of the connection.

My questions are:

1. what is the best way to design the bearing housing?
2. should the bearing be mounted to the frame or the gear? and what are the considerations for doing so?

attached is a simplified design of the parts


Thank you,

5-10% shrinkage ?
what on earth are you printing with - even abs is generally only 1-3%
