Roundhouse 0-6-0 vs DCC/Sound

@ Lutz.

From what you know about 3D printing. Do you think it would be better to make spheric rivets heads or les prototypical cylindrical rivet heads?

Huuuh, how to tell a long story in short? And this story is very off topic too.

Here a link to the manufacturer: <!-- m --><a class="postlink" href="http://waggonfabrik.eu/">http://waggonfabrik.eu/</a><!-- m -->
Sorry in German only, but there are a lot of good mostly self explaining photos
Take a look to this first, especially to the photos of the trucks and truck details => Voith Maxima
Next is => Logbuch
scroll down to the bottom => zu den älteren Logbucheinträgen
Again scroll down to the bottom to the first article.
Scroll a little bit up, then you see the first 3-D CAD pictures of the trucks.
Scroll up to see further photos of the development, especially the trucks.

At least each of the trucks is mounted out of 122 individual parts, in words one hundred and twenty two parts.
When we made the first models for showing on Nuremberg Toy Fair and the mouldings were still in reworking process, it was decided by the owner to print the trucks in 3-D.
With all details well printed on.
So the nearly complete truck with all the details was reduced to a very few parts only. A quick way to made show models instead of pure handcrafting all the parts by scratch.



Only to show the complexty:




Somebody filmed my hands on Cologne Model Railroad Fair:

Rivets.
If they are very small it is esier to make them cylindrical. The human eye would not see the difference.
everybody who is the opinion to take a look on your self build models with a microscope
