120mm Fan Filter

120mm PC fan filter - loosely based around Akasa's 120mm filter: http://www.scan.co.uk/products/120mm-aluminium-fan-filter The holes are actual holes - there probably is a graphical shortcut to save resources... this, however has not got such a thing. Over 10,000 holes in 9 sketches (resource issues) - so it is possibly a little too resource hungry. If you know of a way to improve it, let me know :)
