Sorry for all the constant updates and many thanks to josepezdj for testing.
[PTI] Remix
I'm by the end... I get out from there with the funnel and the cube, having pressed the button to deactivate the upper bridge, but I just can't reach the end part with both the cube and the funnel!! damn it! I'm on it!! 
EDIT
SOLVED!! IMPRESSIVE MAP MAN!
CHEERS!!! Brilliant puzzles! I don't know what part is yours and what part is Gig's since I haven't played the original, but this version is really good. I don't really think there're many different solutions... but after all the time I spent in it, I think there are different routes for doing some parts... 
Thanks for creating! And Gig as well.
Solution Video rendering.... It should appear here:
The intended solution is much simpler than in the video. There's no need to move the cube back into the tractor beam area (redirecting the laser to turn off the fizzler while moving and holding cube would be considered a high-level skill, which my maps don't require).
Thanks for your comment! I first tried to get out with the funnel through the opened portal where the laser beam ends but impossible to reach the other edge! well prevented!
It was an awesome version however... I tried Gig's version after this and I found a couple of unintended moves not present in this, so cheers for a more solid version ![]()
I really appreciate the videos. Thank you so much.

OK, now I should't be able to grab the cube or enter there if the catcher is active... you should separate a little bit more the laserfield from the fizzler to prevent grabbing the cube because I can still grab it if I place the cube really close to the fizzler
Anyway, that's not the important part because I can simply get the cube out from there by placing a portal inside the funnel room and other outside. I need to enter the funnel and now I can't do it my way...
I'll keep on thinking another alternate way ![]()
EDIT: OK try it now.
I felt pretty ninja doing that last move... so I don't really think it's intended... and if it would, I prefer some of the oldest versions tbh...
It should appear there:
Made more edits. I bow before your ninja skills 
Lol, I can't be playing your map all the weekend!
I might try the new version later or tomorrow ![]()
Wow... 5 solutions and videos in one day dude!
Anyway, the map deserves it... I've had much fun today!
Looking forward to your next map!
YES! I can finally sleep well tonight.
EDIT: OK, now that I've seen yours, I found it strange that you did the whole transfer-cube-from-grate-platform-to-button thing twice. You could cut out the steps from 3:00 in the video to 6:00 and it'll still be the same.
But anyway... I do need the cube there in order to make possible the final setting... I mean, I need a portal in the grate floor area and the other in the initial... and for doing that I need to respawn the cube and repeat the process thing again, don't I?
EDIT
OHHH... damn!! I'm stupid! lol you're completely right!
It should have taken me half the time!
As I told you... I was too used to the previous solutions!
