Design files for a low-cost high-resolution imaging device for hyphae in soil

<p>This dataset contains the stereolithography (STL) files for the 3D-printed and cut parts of a low-cost high-resolution imaging device for hyphae in soil called&nbsp;<em>Hyphascope</em>. The design of&nbsp;<em>Hyphascope</em> was adopted from the 3D printer i3 MK3S+ by Prusa Research, with a digital microscope camera (DMC; 600&times; magnification) replacing the filament extruder. Repeated imaging of a soil profile with the imaging device enables researchers to observe and quantify changes in the amount, distribution, and morphology of hyphae.</p> <p>The parts were created and modified using&nbsp;<a href="https://www.freecad.org">FreeCAD</a> (version 0.20). STL files for the original parts are distributed under the Creative Commons Attribution 4.0 International License, STL files for the remixed parts under the GNU General Public License v2.0. For a detailed description on how to prepare and assemble the parts see&nbsp;<a href="https://doi.org/10.17504/protocols.io.bp2l6xo3zlqe/v1">this protocol&nbsp;on protocols.io</a>.
