Threaded Rods Fittings

The threaded rods for Z-axis is little bit too short to reach thru the upper frame. Because of that the z-axis wobbles. It's not a big wobble, but it affects print quality. I downloaded 3d model for fittings from Thingverse (links below). The fittings are very simple. One end goes thru upper frame and other on to the threaded rod. I glued upper end to frame to make it more secure.
