IKEA items used:
Dokument Letter Tray
I took my unused DOKUMENT wire letter tray to make a light-weight drawer to keep the clutter off the desk surface.
Step 1: Cut the letter tray frame
Cut the rails out of the letter tray frame using something like a pipe cutter, hacksaw or Dremel etc.
Step 2: Attach the tray to the underside of the desk
Then I mounted the tray to my desk using 1.75″ wood screws to go through the tube and bite into the desk surface.
