This repository contains the bill of materials, license and all relevant design files for the 3D printable spectroelectrochemical Raman cell described in the manuscript with the title “A 3D printable spectroelectrochemical Raman cell” submitted to the Hardware X Journal. The presented spectroelectrochemical Raman cell enables in operando measurements on different electrode geometries and materials including gas diffusion electrodes. The cell is designed for both conventional machining as well as 3D printing. The aim of the 3D printable design is to reduce the barrier for the application of spectroelectrochemical methods and to facilitate the customizability of the presented cell. Whereas the option for conventional machining allows the use of inert materials which enable the employment of corrosive electrolytes.
