CTC i3 Pro B Z Axis Top Mount

I wasn't happy with the Z axis top mounts I found for the CTC i3 Pro B so I decided to design my own using this existing thing as a starting point. https://www.thingiverse.com/thing:2347358. I think Rasta4i has a great design, I just wanted mine a bit beefier. I think these top mounts will add more strength to the top end of the printer and help reduce flex.
