    Sambista, I respect you because you are doing your own thing from the ground up, not copying somebody else's work.

    If you have not ran into this yet, keep an eye out for it. Using PLA for the base is fine for prototyping work. But the low Tg of PLA will cause it to deform due to friction if you punch on it fast/hard/long enough. Investigating other tougher 3D filaments can be lots of fun

      I never cease to be amazed at the amount of collective knowledge there is on this site and the willingness to share it. Great

        Thanks, Tom. That's kind of you to say.

        I have ABS filament but no thermal enclosure yet, I also have PETG but couldn't get a good first layer. And I imagine shrinkage will differ at which point a couple of prints might be necessary to fine-tune the fit.

        But I think in the short-term, I will just re-print in PLA the one I'm happy with to have some replacements ready to go.

        Matt.

          I guess I'm actually finished... kind of all of sudden. Here's a few photos to wrap up...

              Awesome to see another swivel maker!!! Cool to see some original ideas from you and showing your process.
