Construx is a brand of plastic building toys introduced by Fisher-Price in 1983. Unlike other building toys such as Lego, Construx feature beam-like pieces of varying lengths that snapped on to cubical connector knots in order to build large shapes.
I grew up with these instead of Legos and have many memories of building crazy large toys/builds and playing with them. I also own a 27 Gallon container of them from when I was a kid.
The patent on these expired in 1994, Google Patent US4044497A. So I think this is safe to recreate and share. I've decided to try and recreate some of them to 3d print now that I have 3 kids of my own. I will likely create more as I find the time and motivation if others don't beat me to it.
Printed at .2 layer height with a .4 nozzle using Petg so far that has worked perfectly.
The author marked this model as their own original creation.
