How to create the Axle for my F1 Toy Car?

I need some support on how to do the Axle of my F1 Toy Car, I was thinking of some ways on how to overcome it but still couldn't find the solution.
The Radius of the holes is 6mm as shown Above. 

If anyone could give some support, I would appreciate it!!! 
And send some drawings and models to make it easier 😁

    Please read the Forum Post Checklist. Following those guidelines will make it much easier to get your questions answered. But for now, I don't understand what the problem is. Looks like you just need to extrude a 6mm dia cylinder to make your axel. What exactly is the issue?

    @mahir The 6mm hole is already extruded, but I just need support on the Axel part of the Toy Car for the model to let it move around.

    Make another extrude and select your inner circle of your wheel sketch. Make sure you select 'new' on the top.

    @john_mcclary Thx, but now I just need to create the part 'Axle', so it allows the F1 Car to move, but I'm still not sure on how to make it though. Don't forget this is gonna be made on CAD so I need to find a way for the Car to actually move when the product is done. :)

    You will need to make your document public for us to see it.

    When you click extrude, the top says
    'New' 'add' 'remove' 'intersect'

    You will need to select the area in the small cicle and double check that 'new' is selected. That will output the result to a new part.

    Onshape loves to WRONGLY assume it knows what you want for a boolean condition. It is F@#$ing annoying and I hate how it switches modes to 'add' after your first input. Even if you pre-select a mode at the beginning of the command.

    @john_mcclary Thx u so much man!!, Much appreciated. So when the model is gonna be printed out into CAD, would it be able to move the car in real life? 

    And could you also forward me that as well? 
  • john_mcclaryjohn_mcclary Member, Developers Posts: 3,934 PRO
    Well you should add some clearance to the hole if you're going to 3D print. Also a hole at the ends of the axle for a rivet or screw to contain the wheel.

    Is your plan to print it out 100% as shown in the assembly with the wheels in place? Or were you going to insert a metal rod into the hole as an axle and assembly afterwards?

    The whole model is going to be printed as shown in the assembly with the wheels in place as well.
    The thing is that I want the Toy Car to move as well, when 3D printed

    @john_mcclary You could use the loft on the axle as where the hole intersects with the body but reducing it to (5.5mm or less) and the wheel will be stuck onto the axle so it won't be a problem right? 
  • john_mcclaryjohn_mcclary Member, Developers Posts: 3,934 PRO
    Sure, make the axle shaped like a bowtie or something.

    I'm not familiar enough with 3d printing to say it will roll good enough though. 
  • gurkadam_grewalgurkadam_grewal Member Posts: 10 ✭
    Ok, I'll get my axle piece sorted out, but if the model doesn't go as planned. I'll 3D print where the car can't move. :)

    @john_mcclary Could you send the copy of the Formula 1 Car as you did it above?

    So it doesn't have to be a pain for me to do it

    @gurkadam_grewal - depending on the printer, filament, and resolution you are using, you might want a clearance of 0.15 mm or so for features that you want to be movable after printing.  That's not a guaranteed value but might give you a place to start.  Maker's Muse had a clearance testing model that you may want to use to see the effect of different clearances.  He describes it in this YouTube video:
