Originally I had mini trees made out of steel garden obelisks that were very inexpensive but sturdy, like around $5 each. However these went out of stock and never came back so I ended up designing this to be equivalent but around the same price point so I could scale up.
I used PETG since these are outside, after 2 seasons there has been no noticeable wear on these (about 2-3 months each season). You'll need 4 each of the post models, 2 each of the base, and 1 each of the rings and top.
To assemble, the following hardware is needed:
x20 M3 locknut nuts (4792 from Bolt Depot) - I used stainless steel hardware
x8 M3x16mm socket cap (6382 from Bolt Depot) - these are for the base
x12 M3x10mm socket cap (6380 from Bolt Depot) - these are for everything except the base
64 WS2811 Bullet Pixels (or similar) with 4" spacing. Each vertical strand will have 8 pixels.
~72 small zip ties, one per pixel plus a few to attach the non-post vertical strands to the rings.
