Ender3 x-axis damper plus!

thingiverse

The most valuable upgrade for Ender 3 is the installation of motor dampers! Just believe me, I have printed a lot of mods and most of them are good looking but add almost nothing to the actual printer's characteristics. That is not true for the dampers! You will experience a shocking difference in quietness and a good improvement in ringing-free surfaces at the same print speed. Let's get through it step by step: Extruder damper - the easiest to install, no need for extra printed parts, just find 2 short M3 bolts (you are going to need a pair for each damper). This one is actually not a must. Z-axis damper support: here's my design for it, including detailed instructions: https://www.thingiverse.com/thing:3383222 X and Y-axis dampers - the most important two. New Ender 3 mostly comes with press-fit pulleys on X and Y so you need to print a few parts. This guy made a working design for Y-axis: https://www.thingiverse.com/thing:3245255, however I made a few important corrections to the main body and posted it as a remix. You can find it here: https://www.thingiverse.com/thing:3421203 Now let's get to the point. X-axis damper. Take it, print, install and enjoy! The design consists of three parts. The main plate is a must print. It is designed for the motor with the damper to be installed at a calculated angle so when you tighten the belt it should stand straight and the belt will not wear. You will need 1x NEMA17 damper. You can buy these in large internet stores for $1-2. I would prefer this: https://www.banggood.com/Shock-Absorber-Stepper-Vibration-Damper-for-Nema17-Stepper-Motor-p-1188070.html?rmmds=detail-left-hotproducts__2&HotRecToken=ChQxMDA1Mjg0NTYwMDkxOTQzNDQyNRACGgJJViICUEQoAA&cur_warehouse=CN with the large inner diameter but this one: https://www.banggood.com/Shock-Absorber-Stepper-Vibration-Damper-for-Nema17-Stepper-Motor-p-1064910.html?cur_warehouse=CN also will do if you are ready to work it out with a jig saw like I did. I also recommend printing and installing X and Y tensioners: https://www.thingiverse.com/thing:2986144 Please download a new cover here: https://www.thingiverse.com/thing:3271077 the guy made a great design and that inspired me to enhance it using my ideas and Creality open-source files for the printer. If you want to make custom writing on it like I did just let me know in the comments and I will make an update. The two small parts add a nice feature of precise adjustment of the Z-axis. I found it very useful when you need to change a building plate or the nozzle. You will need 1 M4x20 bolt that comes with the Ender 3 frame. Make sure to screw it in and out a few times before assembling. Here are some updates: - Increased space between horizontal rails - Added angle tuning plates 0.8, 1.3, 2.1 mm These are designed to be printed with 0.2 mm first layer and 0.16 mm layer height 100% infill. Stackable. Just insert it into the main plate before installation. Mind the direction of the thick part! You might need them to fine tune your damper's angle in case your damper is different from mine in terms of stiffness. Note: I made some minor changes to make the text more readable and added a few sentences for clarity.
