Designed for easier printing than the source, because it prints on its back.
Works best with SC8UU pillow block bearings.
EDIT: added a clamp that contains a mount for the 30mm E3Dv6 heatsink cooling fan.
EDIT: added a WAY better clamp that has mounting holes for part cooling fan guides (http://www.thingiverse.com/thing:895483)
COMING UP: diy 3$ autoleveling probe
I am using a 12$ E3D v6 clone with a 3$ PTFE-lined heatbreak it has not failed me in over a year of printing.
