Why only disks?

Make semi-circles, 90°, long straight, and square pieces. And make couplers that will let you attach 2 pieces together without having to rotate the next one 90°; all it would need to be is like a tiny little H-beam. Then you can make flat walls and stuff, plus with different shapes you could design better looking things.

Also, you did right by putting a hole in the middle of the connectors and I like how you have set that uses it with an axle for a vehicle.

Make rods that have cutouts that the disks can click into or clips that will go onto a rod and will accept a disk.

If you can give me some measurements (disk diameter, hole diameter, cut length, and disk thickness) I could mock up some stl's. Can't do whatever click-interlocking thing you got going on, but this post piqued my interest and remixing this type of toy seems like a fun idea.
