A 100% 3D Printed Linear Snap Action Mechanism.

A 100% 3D printed linear snap action prototype mechanism for an upcoming project.

As the name implies, the snap action in this mechanism is linear. The slide (yellow) travels between two leaf springs (white) positioned in the base (green). When operated, the cams compress the springs until the cams reach just over 50% of the designed travel length, at which point the slide snaps to the full travel position.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.7.0, and 3D printed in PLA on Ultimaker S5s.

I'll have to make some of these to have around the classroom to show students different mechanisms for tactile feedback. Always a fan of a good click.

I like the retention choice on the springs, never though of making my spring assemblies like that. Definitely don't have to worry about the print degrading like a poorly built living hinge, in this setup.

Cant wait to apply this to some of my prints. I think this would really make them more functional and secure.

love the mechanical sound it makes, will definitely integrate this to my next project!

This is great! Talk about rising to the challenge. 👍👍

This is a sweet and simple double action mechanism. If I were to give it a name I'd call it a threshold double action mechanism.

Wow - very clever. Love videos like this that help opens the mind. Definitely deserves a subscription and I’m looking forward to see your other content. Thanks for sharing. 👍😎👍

I am working on something and infact i was looking for a locking mechanism, thanks for sharing this.

[LoveMakeShareTV]

This came up in my recommendations and it's applicable to like three projects I'm thinking about! Thanks for sharing!

[alexanderakerhjelm]

thats a really clean, simple solution, well done!

[gnamp]

I love it but can't immediately think of a use for it.

Super cool; this is very similar to the mechanism that gives the Nintendo Gameboy that beautiful click on the power button. All models I believe.

You could definitely turn this into a momentary switch if you add a return spring.

That is very satisfying to hear. I was not expecting asmr clicking.

[makerspace]

I like it. It would be a great teaching project.

Mount a magnet to the central area of the mobile part and you have a perfect magnetic reed switch which can also be used in waterproof applications.

Stupid, ridiculous, worthless YT ads pop up and block the vid. Great job!!
Thanks for sharing.

you could position the moving thing right in the middle and then you can use it to see if a parcel has been dropped or something like that

Most people: thinking about how useful this’ll be for projects
Me: thinking this would be such a nice fidget toy
