i3 Z-frame support bracket for threaded rod

thingiverse

Make these for a mixshop i3 printer, likely compatible with others using the i3 design. These parts will support the frame and reduce wobble. Upper Brackets Instructions: Mount through the back with longer screws into printed brackets that hold the Z-axis guide rods, matching their same hole pattern. Lower Brackets Instructions: Bolt them into the X/Y bed assembly. Extend the threaded rods at the back of the X/Y bed by 170mm, about 85mm on each side, for optimal installation. Both parts are printable without support, although importing may require adjusting orientation due to possible offset issues. Print Lower Bracket upright, double holes facing the print bed. Print Upper Brackets angle side down, with one side having a flat area relative to the print bed at an incline of 19.2°.
