The RisKey Switch: Customizable Contactless Magnetic Key Switch (print *reliable* and SMOOTH key switches!)

thingiverse

Human: Mechanical keyboards and key switches can be pricey, and when just one breaks, you have to discard the entire keyboard. What if you could create your own key switches for a mere $0.04 each? When one wears out after an incredibly long time, you can simply print another and hot swap it out! Wouldn't that be amazing? Well now you can! Not only can you print your own key switches with this design, but it's entirely customizable. Want 2mm of travel? 6mm? It's up to you! What about the feel of the switch? That's up to you too because the spring is also 3D printed. You can select the precise actuation force you desire! And if you don't like it, you can swap the spring out with a new one by removing the keycap and replacing the spring. No need to take everything apart! See it in action: https://gfycat.com/hideousfearfulindri Yes, it supports Cherry MX stem keycaps! It even fits into Cherry MX-style switch plate cutouts/holes! Though, that's customizable so you can make the switch whatever size or shape you want! This key switch is still a work in progress but it should be usable today if you're willing to hand-wire some reed switches. I'm currently learning how to design a PCB that incorporates hall effect switches so eventually that'll be superior, but there's nothing stopping you from taking advantage of this key switch right now. PLEASE REPORT YOUR EXPERIMENTS! There are basically an infinite number of customizable combinations of this thing, and I'd love to hear what people are discovering. UPDATE 20200310: Uploaded version 1.1 of the .scad files which now generate slightly shorter switches and fixes the issue with PrusaPrinters.org completely idiotic file renaming (I renamed the files that it didn't like). There are also lots of minor improvements here and there... You can see what they are in the Changelog at the bottom of the .scad.
