Sorry for bothering, I think orange (not yellow-not red) would be helpful since lot of mid-cheap oven ecc have orange text...

Hi,

It's easy to create your own models.
1. Copy the sh3f file in zip file
2. extract the zip file in a sub-directory
3. update all mtl files with the choiced color (ka, kd, ks)
4. create new zip file
5. rename zip file in sh3f file and clic twice on it.

And numbers together with letters could be useful!

For the numbers, Alax has created them few days ago.

Regards,
bdfd.
