Space navigator storage container for transport. Features: The black/grey stuff (on the screw-thread) you see in my picture's is some graphite for dry lubrication. (update 16-12-2014, Made the cavity were the 3d mouse sits in slightly bigger. Also made the cavity were the knob of the mouse sits in a little bigger from 54 to 56.)(update 1-3-2016, Made a redesign!!)I printed it on my orca 044. Took about 8 hours. I used 2 perimeters and an infill of 40%.
