How to Design Snap On Lid

[ignipotens]

Hello,

New to Fusion 360 and CAD in general. I am working on a project and need to make a lid. The lid needs to snap on and go over the part not inside the part like many of the videos I can find show.

Here is an example of a design that has an indent on the outside for the lid to snap on.

The lid then has the same design on the inside so it snaps on snugly and stays on. What is the easiest way to go about designing this in Fusion 360?

Thanks!

I would start with a sketched Rectangle and then Extrude.

Have you gone through the Tutorials?

If so, can you File >Export and then Attach the *.f3d file of your initial attempt here?

Yep, I have watched two courses in the learning section.

Attached is what I have so far. It is just a basic lid.

I would have started with the center of the rectangle in Sketch1 (Tray Base Sketch) located at the Origin Center Point.

Note that when sketch geometry is fully defined that it turns color.

Thanks for the tip! Do you have any suggestions on how to make the outside feature in the initial image?

This may be of some use.

Thanks! I gave it a quick read and it looks like the guide is more focused on thicker plastic designs. I am designing a thin (1mm) tray and cover.

I can give it a more in-depth read later to make sure I didn't look over anything.

Wow! Awesome response video. This is exactly what I needed. Thank you! I'll clean everything up too to make separate components.

Chris - Excellent video!  I'm new and this was very nice.  I'd like to do a similar lid for a round container.  Do you have another video that shows this?

Thank you for your response.  I've attached the files I worked with.  I eventually created an offset plane, extruded another circle and shelled both sides to an approximate size.  Used the fillet on top and bottom and ended up with a workable piece.

But after watching the video I'm sure my approach is not very 'elegant' and am just trying to educate myself a bit.
