Don't use the cheapest ABS you can find for ANY print. I ended up slowing it down during print to improve quality. I mentioned hatchbox above, but I did not use hatchbox for this print. It was literally the cheapest filament I could find on the internet. Considering the quality of the stuff I used, this print was actually amazing! Using a good, reputable ABS will help considerably, and I strongly recommend always sticking with the more reputable brands.
