Just as the power of the open-source design paradigm has driven down the cost of software
to the point that it is accessible to most people, the rise of open-source hardware is poised to
drive down the cost of doing experimental science to expand access to everyone. To assist
in this aim, this paper introduces a library of open-source 3-D-printable optics components.
This library operates as a flexible, low-cost public-domain tool set for developing both
research and teaching optics hardware. First, the use of parametric open-source designs …
