Spiraled drinking straw cup
Published on March 8, 2013
This model is a drinking cup made out of one long, spiraled up drinking straw. If you suck on the end the fluid will go from the bottom of the glass down and spiral back up again till it comes out of the end.
There is no support structure needed here. I printed mine with a layerheight of 0.1 mm on my replicator 2 and it works fine, I have not yet tried other resolutions. If you print it with transparent plastic, you can see the fluid run through the tubes.
