    Thats a good suggestion Happy. Im liking the castle nut & cotter pin more as it seems like a better way to ensure the nut doesnt vibrate loose. I also like the second version better.

    Thanks for your interest. I will be continuing to test my design and improve as necessary. Ill get back with you guys about production when I'm satisfied that the brackets are performing well.

    Also I assume your interest is in the mounting plates and not the whole assembly with the superstrut and paint job and all that. Thats why I posted my process in here, so others could do the same - if they liked the idea.
    But the mounting brackets are custom so that's what i assume you are interested in. If you guys are interested in the whole assembly, let me know because i don't mind putting together a kit for sale, but then ill really need to put mine through its paces so I don't sell something that wont perform. And shipping would be super pricey i'd imagine.

    I think the mounting brackets are the important part of this design. It looks like they make a solid footprint for any kind of rack that someone would like to use. That's the part I could get interested in if it became available.

    The first iteration was printed with a hobby printer, but the second design was printed with an industrial 3D printer. You can definitely see the difference in the quality. The printer is a Markforged Mark Two

    Posting an update to those who are interested in the crossbars mounting plates. After evaluating the options to have these fabricated for me, the cost would be too great for either machining or for production runs of 3D printing by any company (around $30-$50 per plate 3D printing & $100+ for CNC machining). This defeats the purpose of me doing a budget build of a DIY crossbars.
    Im currently in the process of rebuilding my 3D printer which can print in nylon & reinforced plastics so when/if I do begin to sell these, I will be doing it from home on the side. Once I finish the rebuilding of my equipment, I will begin comparing & testing different materials for a good balance of strength and heat deflection.
