One of my most popular projects has been the etched Altoids tins that I made for the Steampunk Bible article I wrote. For years I've carried one in my bag that I've used for various medications and vitamin pills when traveling. I had cut up one of those typical SMTWTFS pill boxes to make the dividers and while it worked well enough it was a royal pain to get the pills out with my no-so-slender fingers.
I took to carrying tweezers in my bag to for this very purpose. Of course the TSA is of the opinion that 00 Non-Magnet Stainless Steel Tweezers are a threat to the flying public. :-/
Then a friend suggested that I print dividers for the tins on my RepRap 3D printer. Brilliant! and I can incorporate a pair of tweezers right into the design!
