{"product_id":"rack-and-pinion-steering-system","title":"Rack and pinion steering system","description":"\u003cp\u003eThis rack and pinion system demonstrates the Ackermann steering principle, which I have designed all from scratch in Solidworks. It is my first ever 3D printed design so any feedback would be greatly appreciated. \u003cbr\u003e \u003c\/p\u003e\u003cp\u003eIn the images, you can see that the assembly of the linkages is done with thin metal wires - No clue which metal, it was a clothesline! Furthermore, the ‘screw’ constraining the pinion has a screwcap which is very hard to put on as I left 0 tolerance in the 3D model so if you print it you may want to change the diameter slightly, or sand it down.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIn the Bambu 3mf file, the wheels are printed vertically leaving it not to be perfectly round - There is a trade-off with looks vs functionality - If you want a smooth outside print them flat. However, given that they do not spin I would keep them upright. \u003c\/p\u003e\u003cp\u003e\u003cbr\u003eImprovements to be made:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAdd bearings to wheels so they can spin\u003c\/li\u003e\n\u003cli\u003eMake a system which has more realistic scales - make the gears smaller.\u003c\/li\u003e\n\u003cli\u003eConstrain movement to what a real car would use.\u003c\/li\u003e\n\u003cli\u003eAdd a connection point to attach to a steering wheel\/stepper motor so it looks cooler\/has functionality.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIn the Solidworks model - The mates are completely non-functional to let it be animated.
