Because this instructable is a bit more complicated than my previous ones, I'll include a list of materials:
1'x2' 3/4" thick board (any hardwood)
Plexiglas (enough for the two side walls)
1/2" long flathead screws (x5)
1" long 1/4"-20 Phillips head bolt (x1)
Stain/paint (as per preference)
As for tools, I just used a jig-saw, power drill, and power sander.
Step 1: Find a template pattern
I suggest finding and printing out the paper template first before picking out the wooden board, so that you don't buy more wood than you need.
