Hello,
This is

• another slot filler
• another truncated 3x3x3
• another catalan solid never implemented before
• a transformation which retains its shape when only halfturns are used

It even has a strange signature: SharpCorners12488800101A05

Can anybody proove me wrong on the third point?

Wow! I like this.

Very cool shape. Great puzzle!

I really like the shape. I wonder why it's never been implemented before.

I really like that it retains its shape only on 1/2 turns because it can be easily used as a 1/2 turn only cube or a shape shifting 3x3x3.

Cheers,
Burgo.

Very nicely done! The triakis tetrahedron is quite a nice shape, and it is complimented well by the slice pattern of the 3x3x3 cube.
Timur's Skyglobe is a truncated triakis tetrahedron.

Thank you for your comments.There are currently two puzzles in shape of truncated Triakis Tetrahedra in the museum. But still not the non-truncated version although that is about to change now.

I have to correct me: This is your best 3x3x3 mod.
