Shelf with invisible mounting

Small (100x100mm) shelf with invisible mounting. 

It will not support heavy loads but it is meant to be used to display prints, like the awesome support free Mando by czfirz (get it here).

It needs some supports for the clips on the mounting and the guides in the shelf, see attached .m3f. Also notice where the slicer places the seam for the shelf. In the attached .m3f the seam is on the lower right side. Depending on the material and the place where you mount your shelf, you might want to place the seam somewhere else.
