We recommend using supports that "touch build plate only" rather than having supports everywhere. Additionally, while we typically use a 100% infill to ensure water tightness, prints at infill levels as low as 10% were found to be watertight for over 2 weeks. For this print we used black polylactic acid (PLA) filament made and sold by MatterHackers. We highly recommend using black filament to minimize light scattering in the spectrometer.
3D printed objects were designed with SketchUp Make 2017 available free from Google (http://www.sketchup.com/). Designs were sliced using Cura for Lulzbot (https://www.lulzbot.com/cura), a free software that is based off of the more universal Cura software from Ultimaker (https://ultimaker.com/en/products/cura-software).
