This was really fun - a pencil holder with my business name. The letters were printed separately, then each one fit into its spot on the box. The tolerance was exactly right - no glue needed and those letters have no wiggle room.
This was printed in several parts - each letter is separate and the pencil holder was printed as one part with a color change after the base.
