Hi, all;
thank you guys; being remembered this way is an honor! 8^)

As you can notice, I used a protective (movable) cover from an old VHS tape. It's easy to be seen by the known advice (Do not touch the tape inside).
I "carved" it till it fit in place, then I added the small parts that serve as "guides" for holding in place. I used a small clamp to make sure the parts were hold together while the glue was drying out. About the glue: I used super glue, but there are better choices. The irregular surface was obtained with thin sandpapper with a (latter applied)solvent (thinner).
I don't have the main text from the original post, but I may add more information if needed.
Hope this helps for now.
Cheers.
