Feedback on my hub design.

[lemondealc]

Hi all,

I figured a new hub design that offers a cheap and easy way to build domes. I'm basically re-purposing an existing packaging product that is currently used to suspend spools in square boxes. This is typically a throw-away product, which is why it is so cheap. Let me know what you think. 

I recently showed the hubs at the Milwaukee Maker Faire. I had kids building a small dome inside a bigger dome. It was pretty fun.  

 

The domes also held up pretty well to two days of abuse by the little ones. 

Here are a couple of photos (with a close-up of the hub) from a small dome that I built for halloween.

In addition to feedback, I want to let it be known that I have enough of these hubs for about 15 more domes (they are an industrial product and have to be purchased in bulk) so anybody who is interested in getting there hands on them should shoot me an email at lemon...@gmail.com. I'm interested in working with folks who can help refine the design.
