Hey! This thing is still a Work in Progress.
Files, instructions, and other stuff might change!

Description
Parametric grid cube to verify linearity of the entire printing / building volume of a RepRap/3D Printer.
Instructions
This is a parametric grid cube: best edit the .scad (http://OpenSCAD.org) file direct with your printing/building size and create .stl from there.
Note: all numbers in .scad in mm (size x/y/z, spacings and grid thickness)
Defaults: 200mm x 200mm x 200mm with 20 spaces (or 21 struts) with 1mm x 1mm profile.
See also: reprap.org/wiki/User:Spiritdude#Quality_Control
History:
-1.001: spacing per axis definable (xn/yn/zn), see 2nd picture xn=20, yn=10, zn=5
-1.000: first version

Looks like a nice challenge for my Bukobots...
