Tray for Ikea Maximera drawer of 20 cm

I've got some small things lying around in my drawer and alsway they hide themselves from me. Therefor a small inlay that sits on top of the rails and that holds small items like pens.

For reference (first measure your drawer before you print): there is an image with dimensions. The length of the tray is 160 mm (it does fit on a Prusa mini).

Not a world shocking design, but very helpful. I hope you like it as much as I do.
