Modding blowhole question

Hey guys, does anyone know of a site that has tracings for a 12cm hole? I need to draw the hole on my case for a 12cm blowhole but I don't want to freehand it. Thanx

www.baybus.co.uk has them.

EDIT: I normally draw round the fan grill.

 

use cd as ur stencil....

a cd......yes...compact disc....its 120mm diameter....

i use it for my 120mm fan blowhole.....fits perfect for me....

 

sounds good, i'll try a CD or fan grill, thanks
