Tjena Label Holder

I created a label holder for my Ikea Tjena boxes (the bigger ones suitable to the Kallax shelves) which are easily mountable and dismountable without the need of glueing, srewing or something else. The labels you need to print should have a width of 72 and a height of 19mm; the visible area (centered) has a size of 66 by 14mm.
You can print them without supports.
