The box, lense holder, and prism gears are 3D-printed with simple 1.75 diameter PLA. The lense, prism, diffraction grating, and circuitry were added later to make a functional device. The average price on market for an automatic monochromater is roughly 8000USD, if not more, as according to https://www.newport.com/f/cs260-uv-vis-monochromators (https://www.newport.com/f/cs260-uv-vis-monochromators).
