4 Axle

thingiverse

I'm working on a project involving a 4-axle system from 1970 that's got me stumped. I've been trying to figure out how it works, but I keep getting distracted by its length - I initially thought it was 5 units long, but then I corrected myself and said it's actually 4. The measurements are in millimeters, which makes things a bit tricky for me. I wish I had more information about this axle stick, but all I have to go on is my own observations. As an aside, I want to acknowledge that the LEGO Group owns the trademark for their iconic building blocks, but they aren't involved with this project in any way.
