Calibration Piece creation

Hi all,

I need to print some models for calibrating my machine vision system. I need the models to be two tone checkerboard. e.g black and white 1mm^2 on each face evenly distributed.

The parts are quite complex (i.e multiple faces to each one) but not large, largest part approx 15mm (W) x 50mm (L) x 20mm (H)

I would really appreciate some support on getting checkerboard on the models and then how to print it to a good resolution!

So far I have attempted this myself using Blender, but I am an absolute amateur!!!

All the best.
