So you're looking for funny and efficient 3d printed straws for your cocktails, milkshakes and stuff?
These straws use an inner pattern that reduces leaking. thanks to it, depending on your printer, you'll experiment from very little to none of it. For that, you'll need at least 3 walls and 100% infill.
From the simple straight to the exotic filtered Mojito, I hope you'll find the straw that you always dreamed of!
Stay tuned for more models
Various straight, twisted, double twisted and other shapes are available.
Two pipes straws
The Mixers allow drinking from two small or big glasses (The mix happens inside the straw)
Lovers, and even Sheridan's amateurs will also find their own straw. That last one have a specially reduced hole for the white part of the mix.
The Cocktails and Special Mojito straws are equiped with a filter to avoid mint to obstruct the pipe

So, the pattern used to print with an optimal result is relying on the smallest amount if infill directly in contact with the water. Walls are straight lines that have a much better "watertighteness". We then must optimize settings to use these shells properties. The lack of hermeticity of the infill on top and bottom will be opposed by a higher number of layers.
For optimal result:
1) 100% infill
2) 3 walls/shells/contours
3) Autowidth or 0.4mm width
4) 0.2mm layers
5) Extrusion min 100% ideal between 110 and 120%. This really helps with leaking.
6) Nozzle fan (or even ambiant fan) helps layers to stay flat thus also reducing imperfections, therefore reducing leaking.
7) Obviously, a slower print will also give a better chance for layers to be perfectly adjusted and hermetics.
8) In most softwares, there is a parameter for overlap of infill vs sheels. Increasing it may help. **although listed in point 8 because it is very specific, it mayy drasticaly help if you have leaking on bottoms and tops flat surfaces.
9) Printing on glass with a very close first layer will minimize chances of leaking from the bottom side.
This may require some training, but I had some first printed straws that where leaking and I used a lighter (with a blue flame) and quickly runned over the straw flat surfaces and the melting sealed most if the leaking.
