Cooling for ABS isn't good for your print, especially when printing small objects. Your bed temperature should range from 100 ⁰C to 110⁰C, you might corrupt the print if ABS is cooled down hastily, this will cause it to shrink. As you can see in the image above, the top of the pyramid has an issue with extrusion temperature, it was printed at 210 ⁰C and with no cooling. Try experimenting with 220 ⁰C and you’ll get your accuracy.
