Originally, I wanted a little container for loose tea, so I made one with "tea" written on it. (Pretty creative, right?) It's somewhat airtight and watertight because the threads are pretty fine; it's certainly better than nothing. Then I made a few other designs and made them nicely stackable.

I printed them with a 0.4mm nozzle at 0.2mm layers but modified the threaded parts to be made with lower layer heights using the variable layer height function. I also recommend at least 4 top and bottom layers so that the threads get properly supported, but I'm not sure if this is necessary.

Prints without support!

You'll probably need to play around with your settings for the threads since every machine is different.

Let me know if you have suggestions or wishes!
