This is first time I’ve ever seen anybody mention K’nex. I’m from India and they are unavailable here. A relative bought a huge tub of K’nex from the US and that thing, inarguably, shaped most of my childhood. I give K’nex a shitload of credit for being so damn flexible in the sense that you can make about anything with them. I used to make a lot of practical things with them, CD holders, phone holders, photo frames, random ass show piece vehicles, pen stands. Oh man. Thank you so much for mentioning K’nex. This brought back a LOT of memories.
