Neat 3D printed parts!
What did the nylon handles cost you?

Roughly 3.75 each in plastic.
Here’s the link for the shapeways shop I’m working with. He has them available in 2.5” scale in the store. He had to customize mine for 3”.

Due to my funky scale (2"). And the number of handles I need x cost, I think I'll make mine on my own lol.
I've had pretty good luck forming little pieces of brass flat bar, and soldering them to washers in a fixture to make little masts and poles (for stuff for HO scale).

Don’t blame you.
I needed 20 handles in all.
Time vs money, money won out this time around.
I’m to slow getting little details done.
I do plan to make my own grab irons.

What is your thoughts on a using a exhaust silencer on that diesel? I’ve got plenty of room under the hood. I would like to have the exhaust to dump under the chassis. Those little diesel like to coat you in smelly fumes. LOL. The smell reminds of flying in Chinooks.

I think if you made or installed a bit of a muffler and a fair diameter, long exhaust pipe after the muffler, it will offer a deeper more realistic tone. I'm not sure on the size of the muffler, I'd have to see and listen to what it sounds like with the stock one and go from there.
Because my Honda 390 is air cooled and I'm running the exhaust out the stack, I'm ducting some of the airflow up vertically around the stack in hopes of shooting the exhaust upward and over my head. (Keep in mind I'm "engineering" from a riding car though or that stack would be in my face big time).
It will also help keep the exhaust from getting too hot and causing issues with the body/paint around the stack.
I was lucky that the later S-12's utilized a huge rectangle tube stack (Some plans posted on ESPEE say they were 16" x 10"), which I was able to get fairly close to scale using 2-1/2 x1-1/2 rectangle tube.
