L Boxx Pica Dry pen holder

I'd like to store my pens at the top of the L'Boxx so that they are always to hand.

The holder clamps itself in place — no glue necessary.
I changed the colour to indicate where each pen should go.
Currently, there are three versions:
Pica Dry and Pica Ink
Pica Dry and Pica Dry
Edding 21 and Pica white

The left and right sides of the top are different, which is why there are left and right versions. Make sure you are using the correct one.
The colours in the Dry_Dry file should be 'Grün Grün' (green, green), not 'Orange und Grün'.
In the colourless version, you can simply rotate the item to match the side.
