Anet A8 Bed LM8LUU Bearings For Custom Carriage
Description
Designed for the [Gulfcoast Robotics Anet A8 A6 3D Printers Upgrade Y Carriage Anodized Aluminum Plate](https://gulfcoast-robotics.com/products/anet-a8-a6-3d-printers-upgrade-y-carriage-anodized-aluminum-plate), this upgrade aims to use 3 LM8LUU bearings for the hotbed instead of the standard 4 LM8UU from Anet. This allows for easier bearing alignment, along with better stability. **Features** * Easier bearing alignment. * Better stability. * Lighter than stock bearing blocks. * Slightly bigger build volume thanks to a recessed endstop "wall". **Required Components** * 1x **Custom Y Carriage** - The custom placement of holes is what helps use the bearings this way.

I personally use Misumi branded ones to eliminate all play.

You can use the ones that came with your Anet A8. * 6x **Zip Ties** - For securing the bearings. **Printing Instructions** * No supports are needed. * Print all parts exactly as already oriented to maximize quality, strength and ease of printing. * You may use 20% infill for all parts. * You may print all parts at 0.2mm layer height. **Assembly Instructions** 1. Print out the bearing blocks. 2. Snap the LM8LUU bearings into the blocks. 3. Secure the bearings with zip ties. This isn't completely necessary but it may help. 4. Pay attention to the file names to figure out which bearing block goes where. It does matter. Also check the 2nd picture to see exactly how the bearings should be mounted in relation to the custom carriage's holes. * The left side bearing can be oriented in any way. * The right back bearing needs to have the endstop "wall" facing the endstop. You will figure out what this means as you look at it. * The right front bearing needs to have the text "FRONT" facing the front. 5. Tighten the M4x8 screws into the bearings. If you have any questions or found some issues, be sure to comment! I will see what I can do! As usual, I am including the Blender source file in case you want to edit it.
