Good for keeping packets of Splenda, Sweet-n-Low, etc. (or even actual sugar) in your desk at work, or while travelling. The lid slides in and holds firmly enough that it won't likely work loose, but has a thumb-pull for easy removal. Or just don't bother to print the lid and use only the base if you want to leave it out on the counter (or just print http://www.thingiverse.com/thing:20170 instead since it's prettier). 2014-05-22: Slight modification, made it a little taller as I was finding the generic packets are just a bit taller and it was kind of snug even with the regular packet.s
