Magnetic fan holder for extruder fan 40mm anet A8

This is a remix of https://www.thingiverse.com/thing:2067566 by Depaulicious. My magnets were larger and square (5.1 x 5.1 x 1 mm) and I am only using tinkercad, thus I had to remix this. Also the holder got ugly while printing so I modified it to have better support for the top magnet holders. And I like honeycomb pattern.
