Ender 3 Z-Axis Damper Mount

Description

This is a different approach on how to add a z-axis damper to the Ender 3, compared to other designs on Thingiverse. I designed it for my Ender 3 Pro, but it should fit on all variants of the Ender 3. This design has several positive attributes: + Sturdy + Parallel to x-axis + Let's you adjust the distance between the motor axis and the 2040 profile to align the z-axis spindle + The whole assembly slides up and down in z-direction and has "tabs" to align it properly with the aluminium profile Things to know before you print this: - You have to take off the x-axis assembly (no problem) - You need to use the included mount for the z-axis switch (uses M4 threads for the stock z-axis motor mount) - You need 4x M4x10 screws and 4x M4 T-Nuts (I have included a design that accepts regular 3mm thick M4 nuts) Mounting it should be straight forward, but just in case: - Remove the x-axis assembly, take of 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 and align the top ones 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 (dont'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: - 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.
