create a wheel for a RC car
What is the problem?
My 5 years old kid let his RC car fall in the stairs. Both back wheels are broken.

Let’s try to make new ones.
First, lets take some measurements.

The first model that does not work that well
Basically, I want a few cylinders with the same axe and a few boolean operations to combine then. To be noted that the pentagon hole is actually a cylinder hole with 5 dots as a base.

Second try and success: dig into it and make an hexagon

The difference in color in just that the green filament is of poor quality so I changed when printing the second wheel.
