I’m not into K’nex as much now, but I have the Crazy Ball Machine (or whatever its called), and my brother has the giant snake roller coaster as well as several amusement-park ride thingies.
One thing that modern K’nex suffer is the sheer focus on license theme to sustain it’s company.
I have check some original set use bricks in the past, but it seems more prevalent on license theme.
(I have collected a few sets during my childhood.)
I have some loose k’nex pieces, but I don’t know where they came from. My guess is that they came with the big box of toys that my neighbor gave my brothers many years ago. I remember doing a project in fifth grade where we had to build cars out k’nex. That was fun (especially since my teammate let me do most of it)
I like K’nex because it’s something entirely different from Lego. Every once in a while it’s fun to try building something, albeit my stuff isn’t very impressive… K’nex models in general always look much more skeletal and colorful than Lego, and mechanical functions are harder to incorporate, but in turn it allows you to build ginormous things really fast.
Here’s a huge motorized ferris wheel I made a few months ago (actually a ferris octagon lol):
Yeah, afaik most pieces only exist in two or three colors each. Color coding is a core point of K’nex, some boxes even brand it as “the color coded building system”.
The ferris wheel only had one speed, I don’t have any variable motors. I didn’t really figure out how to build a two-speed gearbox or something, like I said I find mechanical functions rather difficult with K’nex. Just uploaded a video I recorded back then:
