Expanded or perforated metal/plastic

Chuck in E. TN:
May not be the right place to post this, but I would like to build a cooling stand for my laptop. It's beginning to have overheating issues. And I'm off work today and snowed in...
I need a source of expanded metal like aluminum, or perforated plastic that can be easily bent or fabricated to the shape of a wedge. I can find expanded steel at Home Depot or Lowe's (I'm in the US) but it is heavier and more expensive than I want to invest in. I'm looking for something like what is shown in this video: http://wn.com/My_Homemade_Laptop_Cooler. I have or can come up with the muffin fan, power supply, switches and potentiometer for speed control if needed.

mklotz:
Is it worth building your own when you can buy one for less than $20?

Chuck in E. TN:
Short answer, yes. I visited the link and saw a review that said the usb connector became intermittent afer a short while.
I like the adjustability of the fans in your example, but don't like powering the fans from the laptop usb port. I use this laptop as my main desktop at home and would provide a separate power supply and speed control for the fans.

Have you tried blowing through the fan and heatsink with an airline?  (Sometimes the heat-sink compound between the heat-sink and the cpu dries up and needs to be renewed - not a job for the faint hearted on most of the newer machines!)

As for the cooling stand, how about adapting a cooking tray? (are they called a trivet?) - the type with chromed rods

perhaps you should clean the fan and fins in the laptop there probably dirty with dust if all of a sudden its over heating then that will be your problem.
as for a cooling platform a couple sheets of steel with holes drilled into it  form a box and install computer fans into that then power them with a 12v power supply
but cleaning the fan and fins with probably solve the problem.
just my 2 cents
