Abstract. 3D printing was used to create an extremely inexpensive colorimeter ideal for use in an introductory college or high school laboratory course. The use of LEDs for both the light source and detector, as well as 3D printing the main pieces, allows for this colorimeter to be made and assembled onsite, providing a system that is both easy to construct and customizable.
