i3 Z-frame support bracket for threaded rod

thingiverse

Make these for a mixshop i3 printer (probably will work on others based on the i3 design). These are to support the frame and reduce wobble. Instructions Upper brackets use the same hole pattern as the printed brackets that hold the Z-axis guide rods, you just need to use longer screws to mount through the back. Lower brackets are designed to bolt into the X/Y bed assembly. (the threaded rods at the back of the X/Y bed need to be 170mm longer than the original size (About 85mm on each side of the bed). Both are printable without support. Orientation seems to be a bit off when I import from my software. Lower bracket should be printed on its size (double holes facing the bed). Upper brackets should be printed angle side down (one side with the large hole is flat relative to the print bed @ 19.2°)
