Just a small clip for two Edding3000 markers. The pictures show my first printing of this design. After printing I realized that I did a lucky guess with the toleranzes and maybe it doesn't fit that well, printed on an other printer. Because of that, I changed the design a little bit to make sure the markers 'click' in right. I attached the clip with an adhesive strip to the fridge door.

Like in the stl-file aligned I printed this design laying on the side so that the direction of the tension, caused by the clicked-in markers, matches the layerdirection.
