Z-Axis Motor Mount and Leveling Kit for Ender 3 V2

thingiverse

I purchased a dual z-axis upgrade kit and the product had some tolerance issues - the z-axis mount wasn't square and the stator housing exceeded the width of the end caps. The net result was a complete inability to mount the stepper motor square and align things properly. This is an entire kit of mounts and tools to remedy those issues, including: o A simple z-axis motor mount with a bit more clearance so that the motor doesn't quite touch the z-axis rails o A set of adjustable leveling brackets for the other side of the stepper motor o A combined mount + leveling bracket (as an alternative to using separate parts) o Some simple washers to account for the distance difference in the x-axis roller bracket assembly o An adjustable spacer measuring jig for the z-axis rod lead screw o A simple x-axis rail level The stepper motor leveling brackets require some hardware: o 2 M3x6 screws o 2 M3x16 screws o 2 M3x6x10 threaded inserts You can see in the photos how it's all set up, but it's pretty self explanatory. You can use the mount+bracket combo if you're adding a new stepper motor, or just add the outer leveling bracket if you want to use existing mounts. The spacer jig is really handy, and I use the x-axis level all the time. I'm particularly fond of the bottom bracket, which I consistenly refer to as the TRON Recognizer. I used https://www.thingiverse.com/thing:4699747 as the base for the design, but pretty much tore it apart. The concept for the leveling brackets were inspired by https://www.thingiverse.com/thing:4073953, which is a great idea but had too many nuts and bolts for me :) Anyway, all these things helped me tune the upgrade kit, and I ended up applying it to the original setup as well. Smooth as silk now. As always, ymmv.
