DBot 3rd Lead Screw Belt Tensioner (easier print)

Updated with all the required STL files to implement the belted Z axis layout as shown. Other files used in the build, but not critical to the Z axis are listed as remix sources.

This thing is a small remix of the original tensioner files by Kldz to make it slightly easier to print. The parts have been reoriented to lay flat on the bed and a sacrificial bridge layer has been added to the tensioner nut holes so that the circular nut holes above them print nicely. Just trim out the bridge layer
