About this 3D model

I wanted to come up with a solution to the Makibox Z wobble that is found in every printer that they make (that's what you get from a $300 printer). After analyzing their design, I found that the Y axis end supports were redundant, allowing the ability to remove and use one of the metal rods. By using this rod and a few 3D printed parts, I was able to greatly reduce the amount of wobble in the X axis caused by the Z lead screw moving the table in and out. Pictures show the final assembly, and a Before and After picture, with the After on the left, and before on the right. Large improvements can be seen in the X axis wobble, and slight improvement in the Y axis. I've gone through several iterations of the Z_stabalizer_Table part, and will likely change yet again. V7 uses a slight clamping force with friction to hold onto the table, which is probably lose it's strength over repeated heat-cooling cycles, but has the best sliding along the rail. Once it loses it's strength, it should be perfect for sliding, and can be held to the table with some high temperature silicone or similar non-rigid adhesive. V6 didn't clamp, but held rigidly and had more friction that I would like. Using a grease on this rod would probably allow V6 to work just as well. I've uploaded IGES versions of the final parts for others to import and modify, as the original parts were designed in Solidworks 2014.
