The magic
There are three blocks and a seesaw to weight.
B is heavier than A
C is heavier than B
But A is heavier than C?
How can it be possible? Can you guess?
The trick
This trick is impossible for wood or injection molding; It's only for 3D printer!
The seesaw is well balanced, C is naturally heavier than B; the trick is in A.
Block A is highly unbalanced by its infill density.
The orientation of block A is important.
If A is toward the end, it's lighter than B on seesaw.
If A is toward the center, it's heavier than C on seesaw.
To print
Use the Piece plate.3mf file to print with my custom infill density.
Or:
A:
upper: 5% gyroid
lower: 99% linear
B: 21% gyroid
C: 27% gyroid
I also include the .f3d file for Fusion360, try make a nicer one.
