Remix of the 8mm Self aligning Igus bearing by mska. Removed the rotating part to improve accuracy, took out the undercut around the bearing support which made it weak, moved the mounting holes so they can be mounted with bolts or self tapping screws from either side, Rotated the part so it would print without supports. Cleaned up the file and fixed a few surfaces. Also added an extended version. Put these on the smooth rods and mark your hole placement then drill. You can use super glue to line these up then drill the holes after so they do not bind. Check out my other designs for more interesting useful things!
Downloaded the files, cleaned them up and mixed the parts together to improve the idea and make it better.
