No offense, but do you know what reaming is?
Reaming is an operation using a special tool used to produce a hole diameter of a very accurate size. Reaming is done by removing a few thousandths of an inch of material from a hole using a spinning cutter of a precise size. 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.
