Caliper 4
 
I decided to change my design on the calipers again.  I felt that the last ones weren’t light and simple enough.  This time around I channeled beams instead of trusses.  The resulting design will come out stiff and light! around 150 grams per the pair to be exact. 

Sadly this caliper will not go through production.  Upon the initial observation it was determined that the middle “hollowed out” section of the left caliper arm is not manufacture-able with what’s available to me at the moment.  SO its time for a revision with the same design cues.
