Linear Bearing Block symmetric with nut slots (OpenSCAD)

thingiverse

The defaults (and the .stl file) are for RJMP-01-08 bearing with the block outer dimensions of the SC8UU for the Anet A8, but you can just download the scad file and adapt it to anything you like. This is a mashup of multiple ideas I found around: Nut slots kinda like in this one: https://www.thingiverse.com/thing:1533880 Printed in two halves like this one: https://www.thingiverse.com/thing:2354665 so you dont need a retaining clip. Made with OpenSCAD so easily adaptable - remixed from: https://www.thingiverse.com/thing:2520976 In addition, the nut slots are close enough to the top of the bearing to allow the M4x8 screws that come with the Anet A8 to be used. You can easily move them ("ND" variable) if you're using longer screws and would like thicker walls. I recommend you use the OpenSCAD file and adjust the "pwt" (printer X&Y tolerance) parameter until the bearing hole fit is just right - it basically should just barely hold the bearing inside (be snug), but not squeeze/deform it at all. And hey, you only need to print half a block for tests (and even use some of the tests after some TLC if they were close enough).
