5x7x9 all extended cuboid

Hello Cubers.
This is my version of 5x7x9 cuboid made from a cubic 9x9.
I made this cuboid only by extending pieces, in such a way to create 3 different sizes.
This puzzle is extremely difficult to make and extremely time consuming, it took me more than a month to finish it. It required 140 pieces to be extended.
The turning of the puzzle is pretty good but because of the complexity and the big number of glued pieces, is not great.
I usually design and cut the stickers by hand, but in this puzzle I ordered ready stickers from Oliver's store.
I hope you like it.

I've been doing similar extensions on a project of my own... much smaller cube though... it's a lot of work. Good job.

By the way, your videos are quite clear to listen to now.

Very nice puzzle again! I can't imagine how many hours it took to extend all those pieces. You have much more patience than I do :)
