Shelf Separator - Organizer

The original purpose of this design was to provide an edge against which to vertically store my MIDI keyboard, but it works as a generic shelf divider.

It's indended to be secured to the shelf; it has shallow indentations for thicker double-sided tape.

Length is 20cm, so it should fit most printers, but it's freely resizable along the Y axis without detail loss, in case it's needed.
