3D Electrophoresis Gel Box
thingiverse
A gel box in molecular biology is employed to separate and visualize DNA fragments of varying sizes by using two electrodes at the ends. The negatively-charged DNA moves towards the anode, pulling smaller pieces through the gel faster than larger ones. I designed a 3D model of this box in openSCAD for 3D printing; however, printers struggle with vertical hole walls, so I've commented out the anode and cathode wire insertion holes. Instead, I'll drill the smallest holes, insert platinum wires, and seal them using hot glue. Both .scad and .stl files are available for download, with the latter being used by makerbots.
