I know C-Bear does a BB that allows you to install 3D+ cranks without spacers, but I was wondering if there was a steel bearing option that utilizes a similar design. This is the C-Bear option for reference. I have a number of bikes running this configuration and bearing life seems to be less than optimal on all of them so I figured a design with less room for water and dirt ingress would be better. ... 30mm-rotor

This one is for PF30, so it might work. Try finding Rotor's compatibility charts to see if they make any specifically for the 3D+ with external cups. You might have to resort to spacers on a quick inspection of their website though :( .
