This is a simple and relatively quick hack that hides your equipment and cleans up the look of the Besta Jagra, keeps the A/V opening cool, and keeps little hands from things they should not be touching.
Step 1: Materials
clear shelf pins (8 of them in a single package, normally used for holding up shelves) - $2.97
rubber bumper variety pack - $3.97
screws (6x1 1/2") - $3.54
furring strips (1x2x8, need 10 feet total) - $ 0.97 each
speaker fabric (from the fabric store, 1/4yd) - $3.25
Step 2: Cut the wood
My first step was to cut the 44" lengths. I cut two, one for the top, and one for the bottom. Once this was complete, a quick trip through the router took about 3/8" of an inch from the furring strips. I did this to make sure the corners were strong and square. This part can be omitted, but I think it makes the overall build much nicer. It does require a router (and a router table helps, too).
After that, I cut a total of four pieces for the height of the frame. The two ends, since I had taken off a total of 3/4", were cut to 5 1/4", while the two center risers were cut at 4 1/2".
