Simple picture/photo stand

Simple stand for a picture or photo. I use it for a photo ~21 cm x 16 cm, but it is quite universal 
it should fit a wide range of photo sizes. There are three variants for different thickness of picture S = [1, 2 , 3] mm.
 

Print settings:

• Layer Height 0.3 mm
• Perimeters 3
• Supports: No
• Seam position: Aligned
