3Dconnexion Space Navigator Case

I used different cases for my space navigator. All designs I used had at least one flaw:
* no space for the USB cord
* if there is space for the cord, it is not very comfortable to put the space navigator into the case

So I decided to create a new design. You can remove the space navigator simply by opening the top lid. If you want to put the space navigator back into the case, just open both lids, pull the cord through the case, place the space navigator in the case and close the top lid. Then flip the case, insert the cord and close the bottom lid.

Do not be confused if you look at the pictures. There is no gasket between the lids and the case. I just used two different colors for printing
