Is your Makerbot Replicator 5G Knob not sweaty enough from building things?
Ever wish that giving your replicator a double-fist-bump before each print was mandatory?

If you wear short sleeves when you go to a gun show and think that your tech should be just as jacked, you're going to want to feel the sweet muscles of this knob, as you grab the future by the fists!

I've included a base model of the knob so you can put your own twist on the design.
