Making my own office furniture: part 6

I continued making filter panels for the under-desk rack. The frames are 3/4″ wide solid oak, with a recess cut in the back to hold the screen. The screen is 22 squares per linear inch (484 squares per square inch) 316 stainless steel. It’s supported by 1/4″ square galvanized mesh, just to make it more difficult to damage the stainless steel screen when vacuuming them clean. The screen and mesh are held in the recess with a bead of hot glue which won’t be visible.

Below is a picture of one of the side panels. Obviously I’m not looking to keep fine dust from passing. I don’t want a lot of restriction. I just want to keep things like pet hair and the like out of the fans in the gear in the rack. The stainless steel screen is 70% open.

I’ve finished assembling three of the four filters. I need more stainless steel screen to complete the final filter. It’s McMaster-Carr 9230T51.
