MakerSlide linear bearings

With an interest in most things mechanical and DIY, I could not help but be intrigued when I found out about a former KickStarter project MakerSlide.  This project allowed for a very low cost, highly reproducible  means of creating linear bearings for extruded aluminum projects.  Though I suspect you could adapt the open source plans to any solid material.  The permanent website has more information: http://www.makerslide.com/.

Rather than having to produce the parts yourself you can just go to the MakerSlide store  http://store.makerslide.com/ and purchase the components directly.  I also recommend checking out http://www.buildlog.net to see the projects that others have made, most with the MakerSlide components.
