In honor of the longstanding tetris rivalry between members of the instructables staff, I designed a set of tetris bookshelves for the instructables office using Autodesk AutoCAD
and new preview version of Autodesk 123D Make
. These shelves are great because they can be rearranged and stacked anyway you like, and you can always make more if you need them. I used a laser cutter to cut the shapes out, making the whole process quick and minimally labor intensive.
