When I saw the contest I felt compelled to participate.  And it just so happened that around the same time I was learning how to print with TPU.  So I thought, wouldnt it be fun to make the fan out of TPU?

So thats what I did.

But of course i couldnt just do the print normally.  Where would be the fun in that.  No, I wanted to do the all Infill trend thats been floating around lately.  So I designed this print with that in mind.

 

On that note, printing this requires a bit of effort.  Youll find that there are 3 files attached.  One is the model, the other is a modifier for the model.  And the last is a combo of both of them that you then have to split to parts in the slicer.

To print.  Import the combo or base model.  If you import the base model leave it centered when you import the modifier and they should overlap correctly.  If not, use the combo, and split them.  Turn the smaller mesh into a modifier.

 

For the base print settings.  No walls, no bottom layer, no top layer.  Gyroid infill set to 20%.  Make sure you adjust the speed and other settings for tpu printing. 

For the modifier.  2 walls and 1 bottom layer.

The print will require a little bit of cleanup because the edges around the paddle will not look so great.  But its really hard to notice after you clean it up.

 

Using the Fan.  The flexible material makes for overall a better fan.  The midpoint of the paddle acts as a little hinge letting it flop a little when you swing it back and forth.  Functionally, I think this hand fan will be hard to beat.  While it might not be the prettiest fan, it really moves some air.
