Hi Daniel. Can you pleae tell me how can I modify the model to eliminate the shocks and the diff gear. I have another differential gear from a scrap rc car. Also i need to replace the steering system such that it will be actioned by a gimbal brushless motor. My 3d printer isn’t that good and I’m afraid to print the model as it is. Thanks.

@andunhill You need to open the stepfiles you want to edit in a cad software that can edit such a format and make your changes there and then export a STL for printing.
I think Designspark can open STEP files. It’s free, check it out!
