Inspired by http://www.thingiverse.com/thing:67893 I wrote this parametric altoids storage generator. There are multiple styles to choose from. By default there is not much play in the room for the tins. So use a well tuned printer, or cheat by increasing the play parameters.I printed mine with 0.25 mm layers using KISSlicer on an eMaker Huxley. Using the default parameters my printer only fits a rack for 5 tins.
