USB Key Cover

This is a cover for a EMTEC USB Key. Should be print in flex.
When remouving the original cover, I see that 50% of the volume is taken by air....

So I decided to design a smaller than possible cover for this kind of key.
Print with 102% scale will be easier to put in place.

Next step is to design the cap of the key, which will be standard for all USB keys.
