This work presents a homemade multirole 3D-printed modular spectrometer (MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV–vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be cheap, flexible, and its inner structure is displayable, making it suitable for a range of applications and age groups. The assembly process allows for a clear understanding of the basic structure of the monochromator, the core component of spectrometers, as well as reveals the connections and similarities between different spectral analysis methods. Despite being easily disassembled, the spectrometer is robust, easy to calibrate, and highly precise, making it suitable for both qualitative and quantitative analysis. This study provides a valuable tool for those seeking a practical and educational approach to spectroscopy.
