Lego-Duplo letter brick

thingiverse

Update (2018/11/18) : -Added digits -Available now are "thin" bricks with reduced height - letters become easier to manipulate, print time is also greatly decreased. Original text: This thing contains a whole set of letters from A to Z upper and lower case. I will add digits and some other letters later. In Montessori education you shall print vowels in blue and consonants in red to help the child make the difference between the two sets.
