Book or Tablet holder

This is a book holder/ stand I designed to hold my books for college. I am in college learning AutoCAD and other forms of 3d design. The size will need to be scaled for each piece. I scaled them to 1882.35 and it worked out pretty good for me. For bigger books, I find that I need binder clips to keep them from sliding off of the stand. I did not think to add a lip to the front to hold a book in place. I may modify it later on. This was printed on an Ender 3 V2, 2 sides and 3 cross pieces are needed. The holder just snaps together.
