    So as I am printing out my parts I have some thoughts.

    Has anyone looked at increasing the rigidity of the 3/4 emt conduit.

    I thought of using the spray expanding foam on the inside of the tubes. It would dampen the vibration and increase the tube stiffness. However I don’t think the foam would survive the vibration that is present in the construct. Maybe filling with something else? Air soft beads or bean bag fill packed in the tubes and then epoxy the ends to maintain the bead placement.

    Thoughts? Yeah yeah just go with bigger thicker walled tubes, I know…

    Putting anything in a tube doesn’t really make it stiffer, it just makes it heavier.
