Ruler stand

thingiverse

People often receive this thing along with other similar items.* The base keeps them from falling over. You can store a small item, such as a 1-inch-wide wooden straight-edge, that fits in there right out of the box like you find at Target for about one dollar. Adjustments let you use it to hold other sizes of rulers and related objects instead. They are standing up pretty level, angled back just five degrees. You can alter that angle, though.
