This is a remix of 3DAndy's Pentominos on Thingiverse, both because I love the Tetris "T" and to provide a simple OpenSCAD example. Even if you've never used OpenSCAD before, you can probably understand the attached OpenSCAD file (which is just a slight modification and reformatting of part of 3DAndy's Pentomino OpenSCAD file). More details at the link below. http://makerhome.blogspot.com
