Went back to round teeth

Increased tooth radius and reduced belt thickness. The teeth mesh very
nicely now and the grip is much better than the original version. After
testing for a few days I'll put it on Thingiverse and call it done.
Tool for deploy/retract of zprobe

Mount this to your frame near one of your towers (inside the accessible
area but outside of your usable print cylinder) for easy deploy/retract.

I designed this because deploying with my belt require too long of a
heat shrink tape tube, which would cause accidental deployment in
certain locations. For retraction, I have a large square bed so that
there isn't a good place to use for retraction without losing print
area.
