Generic 2020 extrusion slide-in lug
thingiverse
From time to time I need to use inserted slide-ins or lugs to attach to things which go onto 2020 aluminium extrusions. I have designed a generic slide-in lug which is snug fit for the 2020 extrusion. It is customizable to different lengths, Use the .scad file, or remix from the sample .stl file. I have printed and tested samples printed in PETG which give a very nice snug fit. You can use whatever material and print settings which you want; however with some materials you may need to compensate for shrinkage for good fit. For use with 4040 extrusion, see thing:5417490.
