Worked a lot on the 3D design, to make it look good, designed a lot.
In the previous frame I left too much space for the tires, especially at the front ones. Now, I corrected it to make the hole just fit the tires, also have an other driving mechanism in my mind.

I was thinking about whether I need metal gearbox and differential, as it will have to deliver a lot of power and the motor’s high RPM. I don’t have experience, but probably a 3D printed version won’t make it, not durable enough, so I’ll have to buy a metal one and fit into the 3d model.
