I designed this to be mountable on an old beat up couch and chair, but you can mount it to really any vertical surface. Prints great in PLA or ABS.
To print I found it easiest to do the base flat on its mounting surface, and the cup upright; once completed, the two prints can be glued together with the triangular base pointing up, as shown in the photos.
Fits plastic cups and soda cans nicely. Should fit most small to medium drinking glass sizes.
