This is a printable slate for writing 8-dot braille. It has two pieces, a lower piece with indentations, and an upper guide. The upper guide includes a centimeter ruler on the bottom end and an inch ruler on the top. The two pieces may be connected by inserting a straightened paper clip through the holes on the left side to create a hinge. This was developed as a way to write 8-dot braille code for writing mathematic and scientific notation. View the original file and more at: http://sahyun.net/projects/3Dprint/objects.php#slate
