Calibration 20mm_OD 10mm_ID Cube

thingiverse

I use this for calibrating parts that don't fit well together. I'd rather the outer be a little too small and the inner be a little be a little too big than the other way around. My printer had been overstepping all x-y bounds of models by a tenth of a millimeter or so, but that adds up when parts are trying to fit together tightly. I found a setting in Slic3r under the advanced tab called "XY Size Compensation" and set the value to -0.16 so it shrinks the model dimensions to account for my printer's error. The cool thing is that it shrinks inner dimensions too so now outsides and insides of my parts are to spec.
