Congrats! Don't worry there are still some here that are unable to post pictures (don't worry bro, I will not mention any names).

What type of filament will/would you choose to make that idler as strong as feasible?

I use Esun PLA+ . It's plenty strong enough.

Before the rest of the 3D printing crew dog piles this post and screams about how PLA is no good - I went to the University of Huddersfield and can confirm: The sun never shines in Huddersfield, and PLA will be fine on anything other than that one weekend a year when they experience 'summer'

Best laugh I've had in a couple days!

I actually find that PETG is more forgiving that PLA for parts under stress. PETG also holds threads better for screws. Some folks just hate PETG and I did too before I learned how to print it. I can get PETG cheaper that PLA also.

My experience was the opposite to be honest - the PETG that I used for our clubs Bailey Bridge has been super brittle when it comes to peeling support material and inserting fasterners. Can't remember the brand, but it wasn't cheap crap.
I printed a few more segments using Sunlu PETG over christmas for an expansion, and it was much the same. I ended up having to delete a bunch of detail from the model to get away from having to deal with peeling support material.

It all comes down to how strong the sunlight is and what the ambient temperature is where you are in the world.

I guess I'm not sure what you refer to when you are saying peeling support material? I will say that the best way to insert fasteners in PETG is to tap the hole first.

When the part isn't flat to the build plate, you will have support material:
