Pop Up and Pop Down (Christmas Project)(Design Parts)

After i get back to my country, I starts to get inspirations by making sketched models

After i made all these sketched models, i have an idea of making a lamp that can pops up and down easily, then i research on different kinds of pop up and pop down lamps to understand how these work out.
Lastly i came up with a few designs and end up with a final outcomes.
