CocoSnaps: 3d-printed magnetic clickers without springs

Name: CocoSnap fidget clickers from Kool FingersVideo: https://youtu.be/2D1s7jOAz_YPrinting Instructions: https://koolfingers.com/3d-prints/printing-clickers/Fidget Clickers generate excessively loud noises for their small size. They are quite simple: a bunch of 3d-printed parts snapped together to capture magnets inside them. Some very smart people say you can't make fidgets simpler than these. We came up with these, and hold pending patents on the concept of fidget walkers - think "walking a magnet with another magnet over a largely uneven surface".You can print these clickers for personal use. Feel free to build on them as well for non-commercial uses. They go under CC BY-NC-SA 4.0 as detailed at https://koolfingers.com/3d-prints/. More on licensing later.This package contains STL parts for 4 types of fidget clickers. Two of these clicker models are available on Amazon for those who can't print, or can't bother getting the right magnets. See later sections. Some parts are shared between clickers, namely the two half shells that enclose a "walking surface" with one of these properties: toggle switch, washboard, bumps and rails. There are also 3MF files for slicer apps we have used ourselves, which you may find useful.MAGNETS REQUIRED FOR CLICKERSEach clicker unit requires a disc magnet to be inserted into a control peg, and another magnet to be enclosed inside the clicker body. The disc magnet needs to be of specific dimensions to fit the small peg. Any magnet that fits the clicker body can be used as the inside magnet. The shape, the size and the magnetic strength of the inside magnet affect tactile and acoustic feedback.PEG MAGNET: a 6mm x 3mm N35 neodymium disc magnet. Most disc magnets found online actually measure 6mm x 2.67mm - these are usable too. Many disc magnets are sold without explicit specs their strength. Most of these are N35.INSIDE MAGNET: we recommend a 1/4" (6.3mm) N52 neodymium ball magnet as the inside magnet. For most PLA prints, this produces a deep bass sound and a satisfactory haptic experience. But they are hard to come by, and are much more expensive than smaller and weaker ball magnets. The most common ball magnets are 5mm N35 magnets (the original Buckyballs) - these are fine and quite usable. But you will likely not find exact 5mm magnets. Many magnets sold under the "5mm-diameter" label are actually 3/6" (4.76mm) ball magnets - they are even weaker. But if that's all you've got, then use them. You can also substitute ball magnets with disc magnets, and even cube magnets, for different types of fidget walker feedback.The clickers on our Amazon store are furnished with the 6mmx3mm N35 disc magnet and the 1/4" N52 ball magnet we recommend. You can purchase these clickers at: https://www.amazon.com/koolfingersWarning: swallowed small magnets can stick together across intestines causing serious infections and death. Seek immediate medical attention if magnets are swallowed or inhaled.SUGGESTED PRINT SETTINGS:Always go to our Kool Fingers website for the most up-to-date printing instructions. And remember that there are readme files next to 3MF files for common slicer apps. These clicker models have been designed with very specific fit tolerance, to make these pieces fit tightly but not much that you can't snap them together. Here are some general considerations:Print with PLA. But they also work with PETG, ABS, etc.They work best printed with 04mm nozzlesUse a 0.15mm layer print profileSpecifically, use a 0.2mm first layer heightand the a 0.15mm height for all subsequent layersTop shell layers: 7Top shell thickness: 0.7 mmBottom shell layers: 0.5Bottom shell thickness: 0.5 mmDetect thin walls: ONSparse infill density: 30%Sparse infill pattern: Gyroid or Grid
