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