Xcelite Hex Nut Driver/Setter Holder

This little holder supports x20 Xcelite mini nut drivers. Specifically, the PS-120 (imperial) and PS-121mm (metric) sets.The design allows for all size printing on the drivers to be seen at a quick glance while keeping bench space to a minimum. Metric on one side, standard on the other.Slice is either 0.2 and 0.24mm layer height, 15% infill, but you can drop this to 10% if desired. Works fine in PLA. Initially I wanted these to be a slip/friction fit, but found it to be too much of a hastle. Even after taking the average of all 20 nut drivers, some were still too tight, others lose. So I decided to make them all lose fit. Future add-on: simple recessed top cover to allow a rubber band around the whole set for easy storage.Remix? Sprung retention? Lid provisions?
