Re: How long would it take you to 3D print this ABS plastic part?

This mold was not actually designed for ABS injection.  I had to use a cheater bar on my injection press to get them to fill, then I had to add extra clamping to keep them from flashing.

 Do you know or have an estimate of the temperature and pressure to mold ABS?
 

"There are various considerations when melting and injecting ABS plastic into a mold. For instance, the melt temperature varies between 170 and 320 °C based on the ABS and mold temperature. The injection molding pressure also varies from 700 to 21800 psi."

I find that temperature hard to believe.  Most references give a high temp of 440F to 480F.  There are a lot of factors that can affect required pressure including temperature, mold design, and the shape and volume of the net part.
