3D model of mr_megatronic. The models were repaired and checked for printability.
In the quest for 3D printed liquid containers, the okay just got okay-er!
While...Show more 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!
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.
