Standard Normal Distribution Design (No Markings)

Technically, all of my second wave of standard nromal dsitributions models stem from this one model. To obtain this one, I combined all the pieces from ayoung's model, cut off the numbers, put them within a rectangular prism, and did the Boolean action of cutting one piece using another (cutting the rectangle using the combined pieces). I then had a stencil-type design of the negative space around the normal distribution (that modal will be uploaded as well). I then did the same thing with this stencil piece and another rectangular prism of the same side, to use this stencil to make what I lovingly called a cookie. This helped smooth out a lot of the little inconsistencies of the model. I figured it was useful to upload this, een though I haven't actually printed it, as it is what got me where I am with most of my designs. Also, I hope to figure out how to make this Customizable so that anyone can set a z or t score (standard deviations) and be able to make a model representing said sc
