A simple little stand I designed up to hold a picture frame. It is designed to hold an object 25 Degrees from vertical, or 75 degrees from the horizontal. I intended for it to be used for holding only a picture frame, but discovered that it could be used to hold a wide variety of objects, such as art pieces, books, smart phones, tables, etc. The stand is roughly 5.75"/146mm tall and can can easily accommodate something 3/8" or 10mm wide. The stand can be modified to suit your needs using the included .STEP file to your liking, or can be scaled to suit within the slicer.
While it was not designed to have this, it may be worthwhile to add some stick-on felt or foam feet to the model, to keep the stand from sliding around on a desk or table surface.
