I’m looking to purchase a support rod for my lens shade to connect to my autobellows. Surprisingly this has been the hardest accessory for my Hasselblad to find online.
Unless there is some ground, tapped, drilled feature to them s "simple rod" doing as I suggested and buying a length of mild steel from a home store or hardware establishment, cutting it to length and sanding or filing the sharp and rough edges off, then painting it with black enamel or paint, is no big deal.
If you do no want to be bothered with it, send me the measurements of these things and I'll do it for you.
