Creality CR10V2 CR10V3 adjustable Z stepper motor bracket (Lower Z Brackets)

thingiverse

After I installed PEI sheet with magnetic base and silicon bed mounts on my CR10V2 3d printer, i have recognised that i could not get the gantry down enough anymore for a proper z offset because PEI sheet is thinner than default borosilicat build plate and gantry hits z steeper brackets when i try to move the gantry down any further. You can see the problem in photos with previous original brackets are shown for demonstration. So i researched for a probable solution online and found out that i can get rid of default z stepper brackets with using alternative brackets that attach to backside of stepper motor. However solutions on thingiverse was for other machines. So i tried to design a bracket from the scratch especially for CR10V2 / CR10V3 using previous designs for different machines as a starting point. Result is very satisfying for me. Solved my issues. I tried to design in a way that no support will be needed for printing and i tried to use default screws with no extra materials at all. But i ended up using 4x M4 size T nuts and support will be needed only for the inner hole of brackets. This design needs minimum supports for the print. And you only need 4x M4 size T nuts other then default screws used on your previous bracket. I placed a hole for the cable and the socket. I could probably just rotate the motor so socket and cable wouldn't interfere with the bracket but i didn't want that and my cables were not long enough for this kind of assembly. Briefly you will need 4x m4 t-nuts. You print lowerZstepperBracketLeft => Just mirror the BracketRight file in your slicer. lowerZstepperBracketRight lowerZstepperScrewShim x4 Don't print brackets in orientation in part photo. Lay the side of brackets on the build plate with cable hole on top. You will use all the original screws from your CR10V3/V2 for assembly. Make sure you place the cable in the hole before assembly. Place ScrewShim parts in corresponding holes on Brackets. It will be a snap fit. I designed ScrewShim parts seperately so that you can print all parts without supports. You can also rescale shim parts in your slicer for z height so you can use other length screws rather then stock if required without the need to mix my design. This design will not only let you adjust your z offset further down but will also allow you to adjust the place of your z stepper motor to better align with lead screws for ensuring less tension on z lead screws. I printed this with Esun Black PETG 245 nozzle temp/ 78 bed temp / 5 walls + 5 top + 5 bottom / %30 grid infill. It turned out great but probably overkill. This is my first useful contribution online ever. So please leave a comment+like and post a make if you find this useful.
