A case for Apple earbud container covers

I really didn't like that Apple earbud boxes were unusable. The mouldings to hold the buds are not removable.
So I designed a base to match the old covers, voila - I present: box with clear lid.

The design has a 1.6mm wall, 1mm deep lip with a 0.8mm ledge. Printed with the Flexion (although a stock print-head should be the same) in PLA at 0.2mm layer height.

Just designed in Sketchup. Experiment a bit if you need to, if the lid doesn't quite fit, scale it by 0.1 up or down.
