This route was first found and executed by Krzyhau nearly 2 months ago.
The beginning is the same as the 2 portals route (ceiling skip). Getting onto the platform with the button is tricky as you have to walk down into the trigger which raises the platform, flick towards the button and jump (1:01 it is a look trigger, so you have to flick near the button area)
Then comes the worst part of the route by far, which is spamming the button until you get a cube that rolls far enough to be grabbed. Not much to say here except that the idea is similar to propulsion catch 0 portals, and Krzy says that timing your presses with an 89bpm metronome can help give the correct timing.
Once you have the cube, boost up to the end platform and then rotate your hitbox around 70 degrees using PPD (check your rotation by pressing against the cube when it is facing the wall, your Y-coordinate should be approx. 1360). It is easy to softlock by getting stuck inside the ending door so try and find setups that work well for you. If you want to learn more about PPD here are some resources:
