[Elecraft] MH3 mic case

I worked in a factory making injection molded plastic items, which I 
presume the mic cases are. If the machines are not adjusted properly -- 
temperature, pressure, dwell, cooling, etc., it's possible to make parts 
that are extremely brittle. Sometimes the stress of assembly and 
shrinkage over time causes them to break spontaneously.

I remember an incident in which an engineer demonstrated a prototype to 
an important overseas client -- and it broke in his hands. Very 
embarrassing.
