Vertical calculator storage

Sized for fx-CG50, fx-83gtx and the fx-85gtx.The base of the indentations are extruded by 15mm to give a sturdy base that won't break. I gave +5mm for each gap to make sure the calculators fit comfortably. Didn't notice that it was too big for my a1 mini, so whoever tries it first, do let me know if there are any issues.
