LM8UU 45mm Rev2 - 8 contacts - Linear bearing

thingiverse

My 3D printer had some unwanted clearances, and I wanted to eliminate them altogether.\nI searched for a model that fit my needs but found one that was only 24mm long, so I created a new one from scratch, with a length of 45mm and more interior space to compensate for the print deviation inside.\nAfter testing the prototype, it worked flawlessly...and goodbye clearances!\nThe design works perfectly if you can easily fit the bearing into the 8mm pole. To do this, you may need to apply some heat to the pole or inside the bearing. Once done, add some lubricant grease for optimal results.\nI tested it on both the Z axis and X axis, and it performed well on X but had issues with my Z axis due to a slight deviation that forced the prototype bearing to work harder than intended.\nAt this point, I've managed to resolve the clearance problems in the Z axis, but if they arise again, I'll invest more time into adapting this type of bearing for my 3D printer.\nYou can see the linear bearings in action here: https://youtu.be/25UFcivvHt0 and https://youtu.be/eRld3kMUvms\nThis upgrade was printed with PLA, but you may achieve better results using Nylon or Teflon.\nIt's a bit embarrassing to admit, but...
