A simple hand fan that prints in 1 piece.  You can easily swap out the logo or lettering in your CAD software.

1 thing I would recommend - the fan is very low to the surface of the print bed which I found made it very difficult to remove by just bending the flex sheet.  That said, this scraper by @sh made very short work of it: https://www.printables.com/model/277302-thin-layers-scraper-tinyergonomic.  It was easily able to get under the thin fan and pop it up in no time.

Please let me know if there's something you think I should change to make it more useful.

I printed in PLA, and it held up pretty well in the heat, but I imagine PETG would work just as well.

I hope you like it!
