Back to the original request now:
Yes, we do. I suppose you want us to tell you?
Here is an example, you can experiment from here:
Take a Tetrix metal shaft. Carefully drill a hole with a #40 drill bit into the very center of one end. Press this onto the motor shaft carefully, to avoid damage to the motor (meaning: Hammering is bad).
Some tips:
Hot metal expands, which may make an interference fit easier to assemble.
Long shafts under radial load must be supported at the far end.
Latex tubing is not very abrasion-resistant.
Rubbing alcohol makes a fine lubricant for assembling rubber onto metal.
Good luck.
