End Caps Aluminum Extrusions
thingiverse
This is an endcap for OpenBuilds aluminum linear rails. I printed these in PETG instead of PLA, and the 20x40 v2 was designed to be a nice tight fit without screws, just snap-in. PETG is more flexible than PLA and less prone to breaking, which helps the endcap snap into place and stay there. I've added screw versions for the 20x40, 20x60, and 20x80 extrusions. They're all designed for low profile M5 screws from OpenBuilds, which have a slightly wider head.
