Parametrizable Toy Tractor Steering Wheel

Original steering wheel on our Rolly Toys tractor broke, so I designed a replacement. The model is using OpenSCAD for customizability and all major parameters can be adjusted easily, with the model changing accordingly. Should also work for other toy tractors/cars, often only with few parameter changes.

There's a triangular cut-out (which can be switched off/removed) that allows snapping in the Mercedes star from https://www.printables.com/model/1033113-replacement-mercedes-star-for-rolly-toys-farmtrac

Model also available here on github: https://github.com/skohlbr/openscad_models/blob/master/tractor_steering_wheel/steering_wheel.scad 

Print parameters:

• Recommend a larger number of perimeters ( >3 ), then it will be quite sturdy, even when using PLA (as I did).
• Used 30% 3D honeycomb infill
• Added paint-on support for the overhanging middle-section
