Miniscope V4 - Base Plate v2

Variant 2 of the Miniscope V4 base plate is designed to be used with an objective module that has the objective module sleeve mounted to it. The advantage of variant 2 is that the physical mounting of the Miniscope into the base plate is now aluminum on aluminum and not aluminum on plastic. 

The objective module sleeve is an aluminum sleeve that is press-fit or glued onto the bottom portion of the Miniscope's objective module. This sleeve provides additional rigidity, repeat-ability, and longevity to the Miniscope mounting mechanism.
