About this 3D model

Build your own bearing!!! Bring your own bbs! This linear bearing has four tubes that are filled with a number of bbs. The bearing has a cap that is held on with two screws. I have now included the 1/4", the 6mm, and the 8mm versions of the bearing External mounting is performed with zip ties passed around the decorative ribs on the bearing. I designed this as a replacement for the linear bearings used within the reprap and maker community. These bearings are louder than a standard bearing. It is important to note that using steel with copper is not the best solution. Steel shot are a better solution, but not as easy as bbs to get ahold of. besides........ These bearings only cost 35 cents to make. Including the copper bbs.
