Profboots DIY RC SemiTruck - Minor Fixes

While printing ProfessorBoots truck I encountered some small issues which this remix fixes: A small hole would appear in the back of the headlight bowls when slicing in Bambu, I've added a small chamfer to the inside end of the headlight bowl to avoid this. The screw the guide says to use to mount the grille to the hood is slightly too long puncturing the grille, I've thickened up the area in the hood to avoid this. I noticed the 8mm screws used to connect the steering knuckle to the axle supports slightly grazed the u-joints. I added some thickness to the axle support to avoid this
