The Minimalist Dual-color Calibration Grid

I have not found a dual-color calibration model that is quick to print and uses the least amount of filament. Most I found were either too tall or too wide which takes quite a bit of time and had to be printed over and over in order to dial in a dual-color printer.

For this reason, I designed this calibration model which literally only takes one swipe of the nozzle for a quick, minimalist print.

For best results, print in 0.12 layer height, which takes two passes from both nozzles and don't use brim (bed adhesion)
