Twisted LMxUU Bearing, Parameterized

thingiverse

I've actually designed a printable LMxUU-style linear bearing with a unique twist - it literally twists around the rod! Instead of simple straight inner grooves, these bearers wrap around the rod to distribute forces and lubrication more evenly. Examples for common sizes are included, along with default 'light duty' versions suitable for vertical applications like delta-style printers. I've also added 'heavy duty' (HD) versions with at least 50% more contact area to handle larger side loading typical in horizontal applications. To see the settings used to generate these examples, simply load the .scad file into OpenSCAD and highlight the section you want to use. Press [Shift]+[Ctrl]+D to remove the comment marks.
