NEMA 42-34 Thust Bearing Mount for Ender 3 V2 Z-Axis

thingiverse

Thrust bearing bracket for NEMA 42-34 motors. I designed this to take the load of the z-axis and gantry off of the stepper motor spindle and transfer it to the stepper motor housing through the use of needle bearings. This bracket was designed to accomodate the uxcell 5mm to 8mm coupler (found here: https://www.amazon.com/dp/B078VTFM1Q?psc=1&ref=ppx_yo2ov_dt_b_product_details) The cutouts near the top of the bracket are to prevent the stock Ender 3 V2 gantry from crashing into the bracket. some fitting may be required depending on your printer. After installing this bracket and associated hardware, your stepper motor couplers should sit flush against the bearings and thereby transfering most if not all of the weight of the carriage/gantry to the motor housing, taking the load off the motor and improving performance. Hardware needed: (4) M3x15mm socket head screws (2) M4x10mm flat head screws (90° taper) (2) M4 T-nuts (1) TC1018 Thrust Needle Roller Bearing with Washers (found here: https://www.amazon.com/dp/B07VZXKWBD?psc=1&ref=ppx_yo2ov_dt_b_product_details)
