Link does not go to picture just tiny pic sign up screen :-(

Got my turbo fans today. Haven't looked at them properly yet.
Also discovered that I neglected to bookmark the link for the 30x30 strut people. So have to find that again.
Been designing the corner pieces (it's all done in my head in 3d). Going to put floors/lids in them so the struts can't go all the way through.
It should help keep everything lined up. I'll also have a short socket for the sidepieces that engaged the slots on three sides, as well as bolts to keep those lined up better.

If you print the pieces with a solid floor for the strut socket - you don't need bolts to keep them aligned vertically with each other. And you could probably have built in feet if you print them upside down. But I think I'll make seperate rubbber feet anyway, as I want the floor as flat as possible for best alignment. Plus I prefer rubber feet.
