Ender 3 Z-Axis Damper Mount

thingiverse

Here's a different approach on how to add a z-axis damper to the Ender 3, compared to other designs found on Thingiverse. I designed this for my Ender 3 Pro, but it should fit perfectly on all variants of the Ender 3. This design boasts several key advantages: + Sturdy construction + Parallel to x-axis alignment + Allows adjustment of distance between motor axis and 2040 profile to align z-axis spindle + The entire assembly slides up and down in z-direction with "tabs" for proper alignment with aluminium profile Things to know before printing this design: - Remove the x-axis assembly (no problem) - Use the included mount for the z-axis switch (uses M4 threads for stock z-axis motor mount) - Need 4x M4x10 screws and 4x M4 T-Nuts (includes a design that accepts regular 3mm thick M4 nuts) Mounting is straightforward, but here's a step-by-step guide: - Remove the x-axis assembly, take off the stock motor mount and stock endstop switch mount - Push the print bed all the way forward - Insert the T-nuts and slide the bottom ones about 50+ mm down, aligning them with the cut of the aluminium profile - Insert the new bracket and align the top screw holes with the top T-nuts. Insert 2x M4x10 screws but don't tighten them yet - Push the bottom T-nuts up until their bottom face is about at the same height as the bottom face of the bracket and insert 2x M4x10 screws (again, don't tighten them) - Push the whole assembly down; the screws should just slide past the print bed - Install the damper on the motor and mount the damper to the bracket (don't tighten these two screws yet) - Slide the assembly down until the motor is a few mm above the bottom aluminium profile - Install the spindle and the x-axis assembly Important note: - With the x-axis assembly fully up, use calipers to measure the distance between the vertical aluminium profile and the spindle. Slide the motor back/forward and fix the two screws holding the damper until the distance down at the coupler is identical to the one you measured at the top - Also check if the motor is touching the bracket. If it does, chances are high that something isn't aligned properly
