PhLAsk

Description

In the quest for 3D printed liquid containers, the okay just got okay-er!

While working on a different project, I needed to make a part that fit to a disposable flask's threaded opening. So I designed the neck of the opening and printed it to check the compatibility with the existing cap. It worked great so I was able to design that project and move along. But I was left with a threaded tube with nothing to do!

The PhLAsk is just a simple hip flash with a threaded cap. I printed it in black PLA at 220 micron layer height, three shells and 20% in-fill.

I filled it with water and left it in a dish overnight and it looks like there is no seeping. The cap doesn't seal 100% but it does so well enough to keep water from dripping out with gravity. A little pressure will cause a seep though. A gasket will fix this.

I have not tested other liquids with different surface tensions but for casual liquid portability, I will be using this little guy!

Bottom's up!

glue a rubber strip under the cap and on top of the flask where the flask meets the cap using food safe expoxy. use natural rubber, latex free rubber bands for the seal. Cut and melt the rubber so that it is the perfect size O ring. Enjoy!

i printed 5 so far, they all leak it's leaking under the thread on the plask hmm what could i do to fix this

So should I print it the way it comes in the file or should it be rotated so the neck is facing up?

Instructions

Print with PLA plastic at .22 mm layer height or denser, three shells and at least 20% in-fill.

Flask goes bottom-up and cap goes top-down!

Use a soft gasket to make the cap seal better.

Any idea how far you can scale it down before

Noob tip: play with the extrusion width (in Slic3r at least) to optimize print time. When I was 3 hours into an 8 hour print I figured out that I could have had a 4.5 hour print by changing the extrusion width.

The flask prints neck-down? With no support? Or does bottom up refer to use instructions?

It prints from its base with no support.

For those asking about the effect on booze, I have printed about a dozen of these for friends and all of them were skeptical at first, but all have said that there's no noticeable taste/effect on their libation. I made a couple out of Abs and coated the inside with food safe silicone, and those also work very well.

Cheers!

Nice! :)

A readily available grab-n-go seal is plastic sealing wrap. Been using it for years to ensure drip-free liquid mobility.

you may also try a rubber "O" ring as your seal. it should hold up under high test as well

Is the material ok to put edible stuff in? It would be a shame to have my scotch melt the bloody container and taste like goop. Outside of taste and a waste of plastic, it would be a waste of booze!

PLA is indeed food safe. It's used to make recyclable cups which are a retail product and used in the food industry to replace stryofoam where possible. It's also used to make medical sutures and implants, etc.

That's a question only science can answer...or experience... Unfortunately have not obtained either. I am curious how the material holds up to "not waters" so I think some tests are in order. I'll probably put some moonshine in this and let it sit for a while.

I only had to see the name to know this was your doing.
