RepRap Benchmark: Linear Integrity
thingiverse
To ensure the linearity of a RepRap/3D Printer's print or build area, generate a parametric grid cube by editing the .scad file in OpenSCAD. Input your desired dimensions and create an .stl file from it. Remember that all measurements are in millimeters. Default settings are 200mm x 200mm x 200mm with 1mm x 1mm profile and 20 spaces. Version history includes definable spacing per axis (xn/yn/zn), as shown in the second picture where xn=20, yn=10, zn=5.
