It’s kind of mind boggling what we can do at home today…
I commend you sir, for making practical use of your 3d printing capabilities.
We bought a stratasys for 80k at work, and have yet to produce anything as useful as that cooling fan of yours in threeee yeeears.
Keep up the good work showing people that they can print things other than figurines and model cars.
I would have carved that fan out of Styrofoam and cast it out of aluminum myself, because that’s what I can do, cause I’m old.
That’s a thirty + year old picture of me standing in a doorway with an uzi.
Please start thinking of building printers with your printer.
Buy an old welding or pick and place robot and stick an extruder on the end.
Try to figure out what BAE is doing with those vats that produce parts a molecule at a time.
Make a machine that makes a duplicate of itself.
Find a recipe of commonly discarded polymers that you can use as a printing media.
You are the future, and you can help bring about the post scarcity society that will end war and hunger.
Well, maybe not all by yourself, but you are on the right track to contribute.
Remember, currency is not wealth.
What is the metal thing?
@NathanielStenzel not sure what you mean?
@mark_warlick thanks!
@Markus_Granberg the metal thing that you put the 3D printed fan on.
@NathanielStenzel It’s a table saw.
@NathanielStenzel an electric motor 
nice
