quick calibration test

I made this to quickly test new filament rolls. Tests how much retraction I need, how it over/under extrudes. I also added small overhangs. Base is 0.8mm and each floor is 40mm tall. Square and cylinder size goes from 10mm to 2mm in 2mm steps plus there is 0.4mm layer on top. Optimized for 0.4mm nozzle and 0.16mm layer height.

Print with 100% infill to test over/under extrusion. For dimensional accuracy / stringing test 10% infill is ok.
