Printable linear bearing
thingiverse
To create a linear bearing, I was inspired by an airsoft ball design. The linear-2.2 version (similar to 2.1 but closed) has minimal friction as the balls form a loop. Measuring 25mm in length and with an external diameter of 23.41mm, it functions effectively. A video demonstration can be viewed at http://youtu.be/GTtfGQe4o7o. To install the balls, you can either insert them during printing or afterward using a plier to gently push them in place.
