Racer with Removable Wheels

This 3D printed Race Car toy was created in Tinkercad and printed on a Davinci 3D 1.0 printer. The file was broken up and printed in two separate runs with two different plastics on a single head printer.
Bolts to hold the wheels are 50 % fill minimum, 0.2 mm height.
The wrench allows the child to easy remove and replace a tire.
