Steering assembly for RC car

Description

Hi there,
Im looking for someone to design and print a steering asembly for a remote control car activity. We are creating a couple generic RC car building sets as part of a training activity. Most of the parts are generic but the steering assemblies are more complicated. We want to make 2/3 different sizes of something similar to what can be seen in this: https://www.etsy.com/uk/listing/1703411922/diy-3d-printed-rc-car-kit-educational?gpla=1&gao=1&
Ideally it would have some spare screw holes to allow for it to be fixed to some balsa wood or similar. It needs to have the axels connectable to a generic servo. We'd like to have about 2/3 sizes and then print each 2/3 times.
Thanks,
Peter
