Spiraled drinking straw cup

thingiverse

The drinking cup is designed as a single, spiral-shaped straw. By sucking on its end, liquid travels from the bottom of the glass and ascends upwards in a spiraling motion before exiting at the top. However, be aware that cleaning this unique design can be quite challenging and it may not be completely leak-proof when printed using common consumer 3D printers (though my particular model only leaks at a very slow rate, taking several hours for complete fluid escape). The print requires no support structure, and if transparent plastic is utilized, the fluid's movement within the tubes can be visually observed. Enjoy!
