My handmade 3x3x4 Extended review(not really)

My 3x3x4 Extended

I made this puzzle about 2 weeks ago, although I remember it was my first creation when I started puzzle making. I made prototype way back 2 years ago and it wasn't too good, and I got busy with other creations, so I kinda forgot about this one. Thankfully, I suddenly remembered it and I got straight to making it. And yes, this is the final version. You need to understand 2 terms here. Fully Functional(sometimes just spelled as FF, not to be confused with Final Fantasy)and Extended.

Fully Functional puzzles are puzzles that are very hard to make but have layers can can all be twisted. Extended puzzles like my 3x3x4 Extended are basically puzzles that have been extended with extra or modified pieces so that it gives the viewer the false impression that it's 3x3x4 when it's actually a 3x3 with an extra layer glued on.

This puzzle turns really well, I lubed it with silicone. The pieces are painted and the cuboid itself looks really professional, although some white remnants of superglue can be seen on the green side. It's also a speedcub-oid as it has adjustable screws. I didn't adjust any of them though.

Don't think that making this puzzle is THAT easy. It requires sawing and sanding(optional if you want a smooth turning product). Making this only took me around a quarter of an hour to make it, so no big deal, really and 2 3x3 cubes was all I needed. I used a hand saw and super glue. I also used a rough stone tablet for sanding down pieces 'cause I'm too lazy to get proper sandpaper.

I'll sell this one for 15 SGD. I can also make another one for you for the same price. Just drop a comment stating that you want one. You can see how this puzzle works here. There are some pictures below to give you a better understanding on how this puzzle works.

It's a speedcuboid!

The centre piece of the extended layer. I used an extra corner piece and sawed off the bump protruding out and glued the piece onto the center cap of the yellow layer.
