DUPLO Car Base 2x6

I was looking for a version of the Duplo car base 2 x 6, but not having found a well-made one, I decided to draw it and this is the result.

For the body:
infill 25%
Supports: NO

For the wheels:
infill: 15%
supports: yes (print with the part that will be in contact with the body, below).

Bye
