Spectroscope

thingiverse

Here's a simple yet effective spectroscope, perfect for working with diffraction grating slides or even repurposed DVD pieces. Designed to print vertically, it doesn't require support but is highly recommended for optimal results. To achieve the best outcome, use a non-transparent filament and adjust your infill settings to prevent any transparency issues. Alternatively, consider placing a black sheet of paper inside the spectroscope to darken the images and enhance visibility.
