Are your box fans tipping over all the time making time consuming costly messes?

These are replacement feet for box fans
(a part seemingly designed to fail universally)

Somehow this project exemplifies everything cool about 3D printing while simultaneously shining an absurd white hot light on its impracticality... The machine cost $2200, the filament $50/kg, it took me a couple hours to make the sub-millimeter accurate model (parts, boolean, fixing the mesh, export, import, slice), and it took about 2 hours to print four feet in fast mode from the MakerWare software.



I included an .stl model of a single foot and a .thing file for a pair of feet saved from MakerWare

They need to be printed on their sides with raft and support.

I printed them using the low settings (I like to print to file on the memcard so my machine doesn't have to drive the machine - that way if I do something taxing or stupid on my computer chat causes a hang, crash, or whatever it won't screw up the print).

Print them, yank them off the raft, pry out the supports and clip into your fan!

Now your fan can stand tall like the proud fan that it is with these 100% American designed box fan feet.

$150 machine makes feet for $10 fan

The design worked perfect, thank you so much!!! It's much more sturdy and the fit perfectly.

I didn't even need these, but I ended up reading through this whole thing because it was so amusing. This totally made my night :)

It's always nice to find this kind of thing and not have to spend all of that time designing it myself. Thank you for taking the time!

Thank you for putting the time into making these available!

Design worked perfect, thank you for posting this 'foot' file, The cheap flimsy ones that come with the fan are easily broken, these seem much more sturdy and the fit perfectly.


This is excellent, just what i was looking for. Using these as a practical demo of the paradox of practical and impractical ways of 3D printing. I love the design, and I am hosting a 3D print night here at MakerBar in NJ to show folks how to print stuff.

Cheers! and thanks for sharing, - M-

The trick is... buy a 300$ printer

Design worked great! With the FDM I was using, I had a bit of a hard time removing the support filament in some of the tight places. In the end, it fit perfectly in my box fan.

Took 1:02 to print a set of two.

Can I just say thank you!!! I have 5 Lasko box fans throughout my house and I think 1 has 1 foot left. This was something on my "Make one of those" list. I printed out 2 sets and they work great. One more thing I can cross of my list! I will upload pics.

I just tossed out a set of those! Should have said something. :P
