Collapsible Hand Fan (print in place)

If you like my models, don't forget to boost, download, like, rate, share and all that good stuff!

This is a collapsible hand fan where the blades interlock in a way that they can't over extend or pass through their collapsed state. 

Warning: 

People seem to have some issues with BambuLab printers with this model. Make sure to have a non-stringy, non-brittle filament and be a bit careful when using the model. It is an ‘expert’ model with tight tolerances, thin walls and small bed adhesion. If this frightens you, please do not print the model or keep it in mind beforehand as a challenge. The issues might also be due to the supplied print profile (although I doubt it), so you might also want to experiment with slicing it yourself.

That said: 

It should be possible to print fine on BambuLab printers and te model should work with the right settings and filament, just like mine does (not printed on BambuLab though). Good luck and if you managed to print one successfully don't forget to rate and share a photo!

The model is designed at 0,8mm thickness and 0,3mm margins, making good bed adhesion and tight tolerances on your printer critical! I have designed built-in ‘brim’ to prevent warping and give extra stability, since a slicer-generated brim would make the model impossible to clean up.

Just snip off the brim pieces and depending on your settings carefully break the wings free (there might be some stringing in between, especially on the top of the print)

I printed mine with a filament swap for a nice detail and for left handed use you can just mirror the STL.

Brimless version:

This has even less bed adhesion and there is a bigger chance your print will fail. Less cleanup though, but you have been warned.

V2 Beefed up version:

Multiple people report breakage (brittle filament or hard handling of the fan) and blades separating (small overlap on the rails and flexible blades), so up on request I have added a version with twice the overlap on the rails and twice the thickness of the stopper. I am afraid that the stringing will be harder to clean up though, both because of the double surface area and because it's harder to peel the blades apart for cleanup. It should be stronger, but I'm not sure it's better. It just compromises in other areas.

Happy Printing!
