SPACECASE

"SPACECASE" is a transport-case for the 3Dconnexion SpaceNavigator
3D-Mouse // metalbase diameter is 78mm // round usb-plug // note its from 2016 maybe it does not fit newer versions.....

3D-Files are optimized for common 3D-Printers.

My recommendation:
PET and HIPS is perfect Material for this object.
It is stable and can be sanded.
You have to adjust the click-connection with sandpaper 200
befor assembling the two inner parts. The upper part should be rotate easily.
