make a Part fit inside another part (with wiggle room)

Hi everyone,

I am an absolute beginner trying to learn by doing and researching online when I can’t figure out how to move on. Now I can’t find any resource to help me, but I think it is because I am not asking the right questions!

I want to design a latch that locks a sliding gate. I finished the bolt part and now I need a case surrounding it. I could just make a different part and measure how big my bolt is and add a millimetre. But I want to try and error it so doing it this way makes it very hard.

Is there a way to tell a cube it should have a hole going through it with the dimensions of another feature (my bolt) ( plus an offset to give it room to slide)?

Here is my bolt:

And this is what I want, only the cube should have a hole through it in the shape of the bolt + a defined offset.

I appreciate your help!

    If you're just doing bolt holes the hole took has some standard clearance settings.

    Otherwise for general applications you can use standard limits and fits. Just note they are intended for parts with good surface finish and control. FDM 3D printers can't do this.

    To do it manually you can:

    • create a hole of the correct size then use the move face tool on the hole surface to create a clearance,
    • Create a sketch with concentric circles and dimension between them to set the clearance
    • Create a variable with your hole size, then create several hole features and use expressions to add a bit where you want the extra clearance

    The hole tool has built in functionality for clearance.

    Hi, thank you explaining these Features to me. I will look them up!

    What I ended up doing was overlaying the parts and using the Boolean function with the offset feature! It worked great!!

    I am aware that this is not the right thing to do when you have complex parts, so I will try and learn more about how to make parts interact better for my next Project!
