CHALLENGE

Build a 4x4 glass door with a rail in the middle that moves away when opening/closing, and is seamless
That’s indeed a nice challenge, I’ll see what I can do when I’ll be back from vacation.
i wont do the challenge, simple because a rail in the middle of a 4x4 door wouldn’t be perfectly in the center. I will try a 3x3 maybe
