3D printed cuvette holder and enclosure
Design methods
We have been using FreeCAD for 3D hardware designs as described in this previous Newsletter. In this project we used the KiCad StepUp workbench to import a 3D model of the Sensor and LED PCBs from KiCad and the A2plus Workbench to create an assembly of the complete enclosure. We also used a 3D model of the PyBadge made available at Adafruit CAD Parts on github.
