6 Sided Die
A 6 sided die created using 123D Design; the STL file that you can download is a 30x30x30mm die.
The design features rounded corners and edges with indented half-spheres to indicate each number. You can easily scale up or down this die depending on how large you want it, here is a list of regulation dice sizes: http://www.dicegamedepot.com/dice-sizes/
I created the design but I used an online 3D Printing service (3D Hubs) to have the model printed because I don't currently have my own printer, therefore I'm not including in-depth printing information.:)
