Rear-Mounted Z-Brace for CR-10 with M8 Threaded Rod

thingiverse

This remix relocates the brace assembly to the back of the printer, allowing full use of the **full printer height** while other Z-axis braces reduce maximum height. This was especially important because my printer is a CR-10 Mini modded for direct drive. As an added benefit, it's a cleaner looking result. I chose to work with Syfeeq's remix that uses M8 threaded rod and M3 screws, as this hardware is more available and provides more than enough strength. This remix includes a newly designed Z-axis bearing block. You will need 2x M3 nuts that drop into the slots. If you run dual Z-axis lead screws, print the same piece mirrored. Reuse the M4 screws used in the original bearing block to mount it to the frame. Also, the bolt recess in the bottom brace has been deepened, allowing for M5x10mm bolts to be used because I could not find any M5x12mm and 10mm is a more common length sold at hardware stores. ### Hardware required: * 2x 60cm M8 threaded rods, cut to length * 8x M8 nuts * 1x M3x25mm screw (top bracket bearing block) * 2x M3x12mm screw (top bracket) * 1x M3x15mm screw (top bracket) * 2x M3 T-slot nuts (top bracket) * 2x M5x10mm screws (bottom brackets) * 3x M3 nuts (top brackets) * Original M4 screws + T-slot nuts If you do not have metal T-slot capture nuts, it works fine to print some. Rather than tap the holes in the aluminium extrusions, I just used an M5 capture nut in the frame.
