Snap 3D prints together with cantilever joint - Fusion 360 tutorial

Cantilever snap joint design for box enclosure in Fusion 360. Easy to design and use joint to combine two 3D printed parts together.
Detailed guide on design considerations for snap joints: fab.cba.mit.edu/classes/S62.12...

[@andyburns]

Not only a good explanation of using snaps, but also a good explanation (for someone who doesn't know fusion360) of the design process, e.g. the difference between sketches and bodies

[@DaddyScribbles]

Awesome. That document you linked was so useful too. thanks!

[@jwisquitethefellow]

Most understandable video I could find on this stuff on the internet. Thank you

[@tomsko863]

BASF also has a free document on how to design snaps that most engineers use.

[@kennethbeal]

Very well done, thank you!

[@user-ww8wl1zi8v]

Very well explained, thanks

[@kulaniscap]

Awesome and very Honest video. 🔥🔥💯

[@joyk1672]

Thank you - very nicely explained 👏👏👏👏🙌🙌🙌

[@aguywithlaptopand3dprinter]

what is your slicer setting to print detail that small?

[@tS-gh9dj]

Good video man

[@Aplysia]

After using the bottom to cut the top, how do you get them to fit together without adding a bit of clearance?

[@snarkfinder2621]

That PDF was handy, thanks. I don't understand the purpose of that lug at the top of the joint. What does it do?

[@dreamonward]

It guides the parts together. So it's easier to align everything before applying pressure that will bend the joint and allow the parts to snap.

[@patstarks]

Great Video!! How did you disassemble the parts?

[@dreamonward]

Pull and perhaps jiggle it a bit. Not the best performing part. I think if you size all the aspects of the joint precisely it should work quite well (see the fab.cbd.mit.edu link).

[@pauloloureirodesousa6145]

Nice video, thanks. Could you please share your project and/or the STL files ?

[@pauloloureirodesousa6145]

@@RuurdMoelker Thank you. As I am going to use Freecad to reproduce your project, I would like to compare the results.

[@dreamonward]

It has been a while, but did you manage to do this in Freecad? I'm looking into other CAD programs now that Fusion 360 pricing has shifted so drastically.

[@hillfortherstudios2757]

How can you dissassemble these? I need a design that can easily disassemble.

[@jonathanviterise1681]

Make a 45 degree angle at the bottom portion in the cantilever that snaps into the recess so it's easier to pull otrather than trying to pull itn out with a 90 gegree connection

[@OttoDIY]

aren't the tabs gonna fail with time? they are quite tall

[@alejandroperez5368]

Yup, this type of mechanism is the worst idea for FDM printers. Those tabs are really weak and will break at the layer lines.

[@smorris12]

Interesting idea, nicely done, but a few observations from my amateur point of view: Inner and outer rectangular lips would be better than the bevel (so the original swept rectangle but on the inner or outer edge of the bottom unit) as square edges are better defined in 3d printing. Draught between parts would give a bit of clearance when mating (certainly necessary for that bevel!) Not sure what the pigtail on the arm is for as it's inaccessible to use as a release lever. The clips are in the Z-axis which is the weakest direction to try and bend a 3d print as layer lines are prone to rip apart.

[@jessejenkins5526]

Editing the cantilever size doesn’t effect the original cantilever size for me, odd

[@Bulbasauros]

I k ow the vid is 4y old, but, instead of extruding ur joint on all 4 sides, u could have used sweep ( for squares, or revolve for circles), it does all the hard work for you.

[@dreamonward]

I don't quite understand what you mean. At which point (timestamp) would you have used a sweep?

[@Bulbasauros]

​@@dreamonward Sorry for the misunderstanding, you did the tutorial correctly and I am at fault.

[@dreamonward]

@@Bulbasauros No worries, we're all learning here.

[@BFun]

Would've been a nice tutorial, had you gone slow enough and explained what you were doing. For a complete "noob" such as myself, this was very difficult for me to follow

[@mrwhodr]

Adjust your playback speed, or accustom yourself with f3d some more before watching such tutorials. I've only been using f3d for a month and I get the idea and also the things mentioned to refer to the documentation for. TBF I've been using 3d programs for concept art but never CAD

[@dreamonward]

There is quite a learning curve involved. I intended to go into an area that isn't discussed in other videos. But search around, there are wonderfull Fusion 360 tutorials around. And I might get around to doing a few beginner videos as well.
