Picture frame with mat, 10x15cm, ECO-Edition ;-) // Bilderrahmen mit Passepartout, 10x15cm, materialsparend

I call it the “eco” version because I tried to design a frame (though visually a solid as the first one) that needs significantly less material to print. Having set infill to 5% you need only 56g of PLA. 

Furthermore I added mat and back for images in landscape orientation. For this frame you need just one nail instead of two to put it to the wall.

Print the border and the mat with maximum layer height of 0.2mm and minimum line width of 0.44mm. Otherwise support for the chamfers could be needed. The back is printable with  other settings.
