In my last holiday I was inspired by a shark. I built this twisty based on a domino.

No I saw other animals!!

Here is a video of assembling: https://www.youtube.com/watch?v=GMVgEKVyG-k

This looks great. The resolution of your 3D printer is quite good and your use of colored plastic is creative. Very nice!

A souvenir from the sixth continent?
The extensions are massive? Once again I am very intersted in the weight o this thing.

Ok, not the most response...

Andreas, the weight is 250 grams. The penguin has a high of 160mm and it it 44 mm thick.

It is printed with FDM in ABS. ABS exist in different colors. All important colors are available, without a good green.
The resolution of the printer is 0.254 mm in each of the 3 directions. I saw it in another threat: This is not good for building complicated puzzles.
But you should know: Every floppy (designed by Door) with very thin legs were printed with this machine. Also all of my 3x3x3 mods and all Minx mods were printed with this resolution.

Since the underlying mechanism is the UFO, does that make this a Space Penguin?

Super cool puzzle
With very much love for the details.
I like it, if people don't think only over maths and mechs but spend some minutes on creativity.

Thanks, Claus!
