Wrapped in plastic to keep as much sawdust off as possible, especially the roller bearings, and taped to deter laminate chipping:
Just as clean as a phaser cut:
A whole 1/4" had to be removed (that's well outside of manufacturing error tolerance) but it now fits properly under the desk:
But another Maverick goof - no grommet hole for electrical....and this is specifically a printer shelf. Since my printer isn't battery-powered, I'm going to have to make another hack. By the way, that unsightly lock on the top drawer will be vanishing - I've got a replacement drawer face coming with the second furniture delivery and will swap it out so all the drawers are smooth except for the handles. Unfortunately it was not an option having no handle holes (100% smooth faces like the hutch doors). I would have preferred to install push-release spring latches behind the drawers instead of handles, but since all their drawer faces are pre-drilled for handles I opted for the most "futuristic" looking handles in their catalog.
I really liked the idea of having the printer below the desk instead of consuming desktop real estate but it's going to interfere with an oversized keyboard tray I ordered (so both the keyboard and mouse pad are off the desk). The printer shelf will need to be placed on desk's left side instead where there's a little more room.
So....I guess it's time to apply another silver stripe while I consider alternate drawer and shelf arrangements for the desk.
