Ender 3 Pro Pulley Press for Dampers

thingiverse

Hey guys, (18.07.2019) important information: after installing the dampers you must check the movement of the y-axis, because of risk of collision of the height adjustment of the plate with the stepper motor. In my case, I had a collision and therefore, I unscrewed the screws that connect the stepper motor with the printer, and pushed it further away from the knob for the height adjustment of the bed. Afterwards, I had no collision anymore. Have fun printing. - - - - - - - - - - - - - - - - - - - - - - - Hey guys, for the ender 3 pro the pulleys are nowadays unfortunately pressed onto the shafts of the steppers. Therefore, I designed a Pulley press, that can be used for x- and the y-Stepper. You put the stepper into the press and with a M5x40 and a M5 nut you can press it out. The pulley is only one-sided pressed onto the shaft. After 5 mm the pulley will drop down. Than you turn the pulley around and press it (using a press, or as I did, using a hammer) too the desired lenght. The best though would be to order GT2 pulleys with screw connections, and use these instead. The distance between Pulley and Press was in my case 6 mm for the x- Stepper and 10 mm for the y-Stepper. Therefore, the design is now made with 6 mm, so that you can use it for both and do not need two prints. If you have a smaller distance, you are welcome to contact me. In case of the press fitting of the pulley I recommend at least 80 % infill. I am new hear and would be very happy to see your makes and get your likes.
