Printrbot Z-axis guide rod attachment

I put this on there because I like the idea of supporting the z-axis rods from both ends. The extra rigidity that it provides is probably marginal, but If you clean the oil off and use just a touch of gorilla glue, it doubles as a lifting handle. I still cradle my baby with another hand but it makes it easier to move around. Not quite as nice as the machined billet Printrbot one, but you're going to love the price!
