I made them at Techshop using scrap wood that was laying in the bins.
What you need = a piece of wood, Disc Sander and a Saw
Make Time = 10mins
Step 1: Mark the Wood
Next, Start Sanding. I used a disc sander (sorry I don't have a picture).
Grind in and rotate how you'd like it.
Step 2: Ohh La La
Just put your nubby ends into the saw and make em small.
Step 3: Bob's Your Uncle
While this idea may seem simple and possibly (stupid) to some, just think. Why pay for plastic based laptop risers that can only hurt our environment and drain our pockets. It will take you longer to find the ones you like and buy them then to make ones that just work.
Thanks for tuning in. Happy day, day !
