Ender 3 Pro Pulley Press for Dampers

thingiverse

Hey guys, Important information: after installing dampers, check y-axis movement due to collision risk between plate height adjustment and stepper motor. In my case, I experienced a collision, so I unscrewed the screws connecting the stepper motor with the printer and pushed it further away from the bed height adjustment knob. After that, I no longer had any collisions. Have fun printing. --- Hey guys, For the Ender 3 Pro, pulleys are now unfortunately pressed onto the steppers' shafts. To address this issue, I designed a Pulley press for both x- and y-steppers. You can put the stepper into the press using a M5x40 screw and a M5 nut to press it out. The pulley is only one-sided pressed onto the shaft. After 5 mm, the pulley drops down. Turn the pulley around and press it (using a press or a hammer) to the desired length. The best option would be to order GT2 pulleys with screw connections and use them instead. In my case, the distance between Pulley and Press was 6 mm for the x-Stepper and 10 mm for the y-Stepper. I've made the design with 6 mm so you can use it for both and don't need two prints. If you have a smaller distance, feel free to contact me. When pressing the pulley onto the shaft, I recommend at least 80 % infill. I'm new here, and I'd love to see your creations and get your likes.
