Summary

This design provides a set of 6, 8, 10, 12, 14, and 20-sided dice.
I designed the dice for helping teach children arithmetic. The dice utilize the font "Oncet" from Google Fonts because the font's clean while the "1" and "7" are still distinguishable.
For generating the initial shapes, I used OpenSCAD the D14 die and Blender for the others. The numbers and some of the beveling were added in Autodesk Fusion.
Printing seemed to work best with PLA and tree supports, with a 0.12 mm layer height.
This design has been superseded by a customizable design written in OpenSCAD.
