Could be used for transport/storage of some flavored body-building powders e.g. as my wife does...

Print one cover, one lid and as much bodys as you like. Orientated as in the picture and WITHOUT any supports. Layer height of 0,1-0,15mm prints well with the threads. Using Slic3rPE with its variable layer height I printed the threads with 0,1mm, transitioning to 0,25mm for the body.

Made with PETG from these guys https://www.3dpsp.de/ as all my other printer parts. This stuff turned out to be quite fine to process. It is quite sturdy, no problems with adhesion at all. And really nice and brilliant colours for a reasonable price.
