Originally, this plate is in smoked plexiglass, but I don't find it very aesthetic, so I made an identical plate that you can print and therefore take the color you want.

Personally, I took the file and I reversed it, so that the printed part in contact with the plate is on top, I use PETG with a textured plate, so the textured rendering will be displayed on top by inverting the meaning of the file.
