Remixed Damper - Duplicator V2.1(Wanhao, Maker Select, Etc..)

I haven't gotten to the printing part yet, but I just bought a Duplicator (MIcrocenter variant) 2.1 and am looking at all the great mods out there. Saw this, and heard it made a bad hum, Though I'd try to increase the surface area to decrease the hum, but keep the spring mechanism. I don't know if it will work yet, once i get printing this week, I will update.

I suggest ABS. PLA is too brittle, imho.
