This bracket is easily printable on nearly every printer and allows a NEMA 17 motor (or anything that has the same front plate dimensions) to be mounted on a European Standard 2020 or 20xx extrusion.
Why I designed this
My FLSUN Cube 3d-printer kit arrived with a broken Y-Axis motor bracket.
The Y-Motor is a NEMA 17 motor that gets mounted on the 2020 frame of the printer using a basic plastic bracket.
Therefore I quickly designed this model to still be able to finish the build.
I quickly printed this model using blue PLA on my Anet A8 3d-printer. See the print result on the images above.
The settings above reflect how I printed this model. You can choose to go with whatever you find applicable.
Besides the ~10mm long M3 screws for the motor, you need two ~10mm long M4 screws with proper T-Nuts for mounting the thing onto the extrusion.
