Led advent candlestick

A candlestick with replaceable leds and resistors, I first made this kind of as a joke, I'm studying electrical engineering and i was going to bring it to the university.. But now I'm thinking that this should be a great way to learn about electronics and led for kids, so I'll probably bring it down to Komtek! It's sort of like a Swedish makerspace for kids, to create an interest in technology and spark creativity.

So, print it, play some with it or give it away to someone and let them learn how leds and resistors work!
