This is a casing for a 3D Connexion Spacemouse Wireless. It's a very useful thing for travelling people who use this ingenious gadget very often. ;-)

Edit:
Because of the request of DArkwIng2, I made a new version of the top. In this new version you can plug in the wireless usb dongle.
For everyone who printed the old version, you can print the "dongle_holder_single.stl" and join it with some superglue. I made this by myself and it works very fine (picture).

I built this with 0.05mm layer height. But It is also possible to build this job with higher layers I think.
Use a support structure for the top.
