I’m super pleased with the diffusion panel as it stands right now, but there’s one thing I’d like to improve on.

I really don’t like the couplings as a means of joining two spars into one. It’s bulky and far less refined than I normally like. Sure, it works in this prototype, but I need a better solution, so I drew up a hub to be made from delrin or some other plastic. It’s out for quote right now, and if I can get it made inexpensively enough, I might just have a bunch extra made and sell them to anyone interested in making their own. The design includes a hole through the center face to allow for a post of some sort so that it can be mounted like an umbrella in a clamp like these. It also includes other holes on the face (at 12, 3, 6, and 9 o’clock) to allow for other accessory attachment points. It’s a pretty simple design, but I think it’ll make this project that much nicer.

I’d like to make another diffuser or two as well as a couple of reversible reflectors based on this design.
