ElementBook Braille version of the AAE

From Roy Alexander of the AAE (Alexander Arrangement of the Elements):

"My [first] contribution to celebrate this Year of the Periodic Table is to reach out to folks who have yet to see what everyone's talking about, so they can get the feel of it: a 3D periodic table in Braille."

For the premise for this PT, here.

For your own model (with Braille) of the ElementBook: print*, cut out each part at the outside blue lines, etc.

The ElementBook Braille version of the AAE is in the beta-test phase for the rest of the year, so if any of you know of an aspiring chemist who would be willing to use it while learning (and keep me informed of that experience all year) send them to www.chemicalelementsystem.com/braille/
