Rev Robotics Extrusion slide

thingiverse

These are slides for Rev Robotics extruded 1" aluminum. These allow linear motion without having to use wheels and bearings. I printed mine with 4 walls and 50% infill. I posted a picture showing how it is almost completely solid. I printed them vertically and have not tried horizontally yet. I included the .dwg file so you can modify it easily for your needs.
