Spent most of the last two weekends building a 10 foot mega tree out of 3/4 inch conduit and PEX, with 3D printed joints holding the whole thing togehter. Ran 16 strands up the front face plus a star on top, all plugged into a controller running WLED. Zero soldering, everything connects down at the base ring, which was the whole point because I did not want to be fumbling with connectors on a ladder in January.
The print quality of the joints surprised me. I used PETG with extra walls and they clamped down on the conduit tight enough that the tree barely wobbles. We had a nasty gust front come thru two nights ago, probly 40 mph, and the thing just shrugged it off. No sag, no strands slipping. The base ring weighted down with a few pavers keeps everything planted.
Biggest lesson was checking my power injection math before wiring anything. I sketched the whole layout on paper first and figured out where I needed to feed power in rather than just daisy chaining everything and hoping for the best. Also left slack in every strand near the top because conduit flexes a little under load and tight strands pop out of the clips. First full test run last night and the wife actually came outside to watch it. That's when you know it landed.
