Compatible with my remixed Ender backplate. Recommend printing with PETG.
I've included the step file to make it simpler for remixing.
The author remixed this model.
I changed the mounting so that you don't need to rotate the stepper motor. Added bracing and thickened the top as the original design flexed a bit. I've adapted it fit with back plates that have an H2 support brace 6mm high and 11mm or less width.
This is fan gives excellent part cooling - excellent to 70 degrees overhang in all directions.
