Trays for O3Q interferometer experiment

At o3q.de you’ll find a great 3d printable set for interferometer optics experiments. I made several trays to hold the parts and transport them easy lie to the class room. In total they hold the parts for 8 sets for student groups. I printed them on a big printer with a 0.8mm nozzle and a 0.5mm layer height since they are quite big. At onshape.com you can find the fully customizable parametric CAD models (e.g. smaller size and/or different labels).
