Arch construction help

[Indigogyre]

Did you use 32 mm ID / 38 mm OD Air Seeder pipe?

or 25 mm ID / 32 mm OD pipe?

What sort of LED strips? 30/m or 60/m ? 5V or 12V?
Has anyone tried seed pixel strings at 20/m ?

If I have to buy a whole 30m roll, I might as well do the whole front fence.

Nice little display and I'm not going to make an arch comment but an other comment. If you can, I would put in horizontal eaves and some vertical outlines on your house as they are simple and add a lot of impact.

For strip, I'm in the US so use 12v since my pixels are 12v I don't have to care about different voltages. I prefer 60/m since there is less shadows. My arch bases were also 3d printed.
