    Believe the shrink factor is 2% with the blue stuff. The gears harden more after 24 hours.

      How do I apply "by volume" to a print scale factor?
      I printed a Lego gear with an opening of 4.85mm, after printing it came out to 4.75mm. My calculations for it came to 2%.

        Well, 1.06^(1/3)=1.02
        So the 2% is right

          Going to make the test print now scaled to 1.02. Yes, of course. The hole I measure is in one dimension, but the whole thing scales up, all makes sense now.
