1x lumber storage bin

I designed this storage bin to fit over a cross rail on my computer desk that is a standard 1 x 4. This will fit over any standard 1x dimensional lumber, ie 1x2, 1x4 etc. Internal size of the bin is 6" x 5 3/8" x 4 1/8" Deep. Do NOT scale in slicer or it won't fit the 1x lumber. Print bottom down and enable tree supports.
