Finally ...
This unit has been a long time in the making and initially started life in our workshop back in 2013. Since then the design has been heavily-modified and improved however, with new hardware being employed and various profiles and sizings sharpened where possible to better reflect the dimensions and 'feel' of a real unit.
The above shot is of the GCU475 sitting in a box that's been designed around it being used in a desktop situation as opposed to the normal simulator environment.
Some photos to show the backlighting
(with special highlights given to the dust!)
For some context, the photograph below shows some of the earlier design work, although this has now been totally re-worked.
