Overview:

I have two sets of taps that I use for my 3D prints.  One is a small imperial set which is a 1x2 bin, and the other is for metric and imperial (a 2x4 bin).  They both have a space for a handle and are labeled.  The larger one also has a spot for corresponding drill bits and BamBam Design’s tap wrench which works great:
