Acetone works very well to bond ABS parts together, but it works even better if you use acetone with some scrap ABS already dissolved in it so it can fill gaps. Parts glued in that manner are just as strong (maybe even more so) as the bond between layers. I use it all the time and find that it actually holds better than CA on PLA parts.
