Before assembly, the support must be removed from the intersection of the circles. It requires patience and manual skill, so I would ask you not to under rate this model because of this.
Made in a very short time as a Christmas present. So I'm sure it could have been done much better but it's still very nice.
I used a cold white light string bought on aliexpress which was 2 meters long. I think much longer would have worked well too.
Materials used. PLA silver and PLA China red for their ring, however the holder plate and stand are made of PETG material.
