Hi, I'm trying to find a small tool to generate basic 3d mazes for later editing. Does anyone know sth like that? Thank you in advance.

Why will a 2 dimensional one not work?

http://www.shapeways.com/blog/archives/654-tutorial-how-to-create-your-own-ring-in-blender.html is targeted at creating products for shapeways, however the same principle will work with a generated black and white maze.

A quick google turns up this site http://www.billsgames.com/mazegenerator/ which i have used before. Combining these two things should create editable mazes.

Best of luck,

Kaine
