Heyhooo
Here I have two prusa/ printable fan beads for you!
I like them both but it is up to you to choose one! For the dual color version you will need a MMU or XL though :)
Sizes:
The Single colored version comes in 3 sizes for the rope: 3 mm, 4 mm & 5mm.

The dual colored version has my standard bead hole size of 6,2 mm in diameter.
Scalability:
The beauty lies in the detail :)
The scalability of the dual colored version is determined by your printing capabilities (especially if it gets very small) - but with the single colored version it is quite easy to scale em!
Choose the inner diameter closest to your rope size and then scale the parts up/ down accordingly.
For example I like a 4,2 mm diameter for PTFE tubes. Calculate 4,2/4 mm (closest version) = 1,05. So the scaling factor would be 105%.

It is also possible to scale them only in z direction to create an oval shape.

Have fun!
