I'm still busy for upcomming Christmas !

My "Leaping Arches" are also finished since today.
diameter = 160 cm
You need a piece of WS2812B LED strip. (2x 78 LEDs in parallel, use the 30LEDs/meter strips)

Watch it in action here:

You need to print 15x bottom and 15x top. (about 1.4 KG PLA needed)
Connect them together with M4 bolts/nuts/washers. (12 mm long is enough - you need 56 bolts/nuts)

Put a piece of WS2812B LEDstrip with 78 LEDs in the upper section of the arch, and another piece of 78 LEDs in the bottom section of the arch, and glue it in place.
I glued the top-parts also, but left the 2 outer top-parts not glued, so I can take them of, if I need to change some wiring ...

Enjoy !
