Printer Stand Hardware

I made this to build a printer stand with leftover 1/2 plywood I had. It is made to fit #8-32 1" inch flat-head screws and associated washers and lock nuts (8 of each). I also added castors from a moveable clothing rack that my wife bought, but didn't install. Cut the plywood to desired size x2. Attach all the corners, they are all the same direction. Drill 4mm holes into the plywood where the screws go, Assemble both layers together with the 4 posts. add small clothing rack casters for mobility.
