Cr10 X axis Brackets Direct drive, linear rails improved rigidity

thingiverse

The standard CR10 brackets exhibit a notable spring back or flex in their bent sheet metal construction, specifically on the X-axis brackets. This phenomenon is further exacerbated by the slop resulting from deflection of the X-axis brackets during Z-hop operations. To address this issue, I aimed to relocate the leadscrew slightly farther away from the frame to facilitate easier vertical alignment between the Z motor and the bracket. These new brackets utilize the standard 3-spacer holes but have omitted the Bowden extruder mount. Additionally, they feature braces to capture the lead screw's captured nut, thereby reducing deflection. Notably, these brackets also incorporate nut captures. Designed to work seamlessly with a linear rail kit that employs the standard 3-hole spacers, these brackets are incompatible with wheel or Bowden setups. The leadscrew captured nut boasts two distinct hole patterns: one aligned with the conventional 16mm center distance and another closer to 15.5mm for use with anti-backlash nuts. R2 Update: Nut capture holes have been added for the lead screw nut, and areas of the bracket have been thickened for enhanced structural integrity. R3 Revision: Hole spacing and sizes have been corrected to accommodate a 18.5mm center hole spacing suitable for POM lead screw nuts.
