This can be printed with typical settings nothing special.  If you want to print without support print with the threads facing up.  The Rim threads are tapered for easy threading.  Great for campers to hold small items (aspirin, fishing hooks or matches).  If you a hunter it will fit in your container or belt for holding shells.  It protects the contents from wet  weather or even shallow submersion.  I use mine to store extra screws and nuts from my Prusa printer kits.

Let me know what you think for improvements always looking for suggestions.  

Thank You
