USB Desk Extension

My PC case has no front USB3 so I extended the ones from the Mainboard to my desk.

Cables used http://www.dx.com/p/super-speed-usb-3-0-male-to-usb-3-0-female-flat-extension-data-cable-black-200cm-230132#.VrUCx1noIik

P.S.: The model was created with FreeCAD, exported (STEP-File) and refined in Solidedge ST8 Academic Edition (*V2.STL/PAR) so the PAR-File probably cannot be opened with the commercial version - sry!
