This is a remix of the Large Key Holder with Shelf by Gerardorl. I removed the nail holes and key holder (as I didn't need them), and widened the wall supports going down to fit command strips.

The widths identified in each file are the width of the command strips you can use with that shelf. Command Wall Shelf 17mm - Use 2 x 16mm wide command strips Command Wall Shelf 22mm - Use 2 x 20mm wide command strips.

You may need to shorten the length of the wider command strips a little as he length of each support is only 60mm (2.35").
