Linear Bearing Block symmetric with nut slots (OpenSCAD)
thingiverse
The defaults and STL file are designed for RJMP-01-08 bearings with outer dimensions matching the SC8UU for the Anet A8. However, you can simply download the SCAD file and adapt it to your specific needs. This design combines elements from multiple sources: nut slots similar to those found in https://www.thingiverse.com/thing:1533880, a two-part print like https://www.thingiverse.com/thing:2354665, and OpenSCAD compatibility for easy modification as seen in https://www.thingiverse.com/thing:2520976. The nut slots are positioned close to the top of the bearing, allowing M4x8 screws from the Anet A8 to be used. You can adjust their position by modifying the "ND" variable if you're using longer screws and prefer thicker walls. To ensure a precise fit, I recommend adjusting the "pwt" parameter in the OpenSCAD file until the bearing hole just barely accommodates the bearing without deforming it. Printing only half of the block allows for testing and adjustments as needed.
