Inductive holder Add-On for Sarf's groove mount adapter

I just got my Inductive sensor and modeled this thing. This is for those who preferred to use inductive sensor instead of servo due to several reasons, me included. I'm using sanguino board that doesn't have any servo control port and by using inductive sensor for auto bed leveling is the way to go for it.

This haven't been tested yet but should work out well with my groove mount without printing a whole new groove mount
