This is a wall decoration made of a barramundi fish bone. I chose to print it using black and PLA Glow

There is a keyhole slot behind the "canvas", which is convenient for hanging it.

This is a cool decoration that can also be used as a sensory learning aid or to provide art or fun for the visually impaired.

I like the Hilbert curve as a surface pattern. If you don't like it, you might want to change it.

I added support to the lock hole groove, but it might not be necessary. However, it can be easily removed.

I grant a commercial license allowing the sale of printed items with my signature.

This is a demonstration of the effect of PLA Glow
