Z-stabilizer Robo 3D R1

Z ripping defect fix. We design and test these z-stabs to improve our printings. We have found that our helical couplers are wobbling and with help from our friends in Robo 3D we came out with this option. Print it with 0.2 and make sure that the gap between the soft rod and your stab is less than 1mm. Also make sure your z-axis goes down and up smoothly.

These is our first prototype and you can see our Stormtrooper print at 0.2mm on 150% speed using Simplify 3D.
