It's a converted chair. I wanted something to go behind my controller that could be tilted, raised and wheeled around. Fucking up an old chair was the best option.
This is what it looks like in place.

The approx measurements of the VC are;
Height (highest point from base): 6cm
Width (left to right): 46cm
Depth (front to back at base level) 18cm
All include wooden side panels. The height measurement doesn't include the knobs either by the way.
