Open Source Optical Rail from OpenBeam - Magnetic Base

thingiverse

The Open-Source Optics project, developed by Michigan Tech's Open Sustainability Technology Research Group, transforms an OpenBeam into an optical rail. An optical rail is a long, sturdy rail that allows easy mounting and shifting of optical components such as light sources and lenses. By replacing the commercial optical rail ($380/m or $115/ft) with Open Beam ($12/m for black anodized), costs are significantly reduced. OpenSCAD code is provided for printing on a 3D printer, with the stl flipped before printing. To assemble, use an M3 screw and nut to attach the rail to the OpenBeam and fit the magnet on top. If no metal base is available, two T-brackets can be used instead. Additional mounts, such as 8mm rod holders and side mounts, are also available from Thingiverse. Obtain Open Beam from openbeamusa.com and magnets from rare-earth-magnets.com. The project is part of a larger initiative to reduce scientific equipment costs using open-source hardware.
