Very little stress is imparted onto the part to do this; certainly less stress than drilling a hole, and it's a reasonable suggestion here.
3D printed parts are more or less always substantially weaker than injection molded parts of the same geometry and material. There are very few material choices for 3D printers that are potentially stronger than injection molded polycarbonate, and it is reasonable to assume none of these materials / printers are within the reach of FRC teams.
And here's the kicker - in order to get accurate bore diameters using 3D printed parts, you would probably want to team the hole afterwards anyway.

I know what reaming is thank you but I appreciate your concern, but injection molds can be structurally compromised from even small modifications. My team has modified the CADD file of the part, combining both halves into a solid part and filling in the empty space around the bearing socket. I will gladly share this part if it works after our testing.
