Snap together chain fidget

pinshape

I wanted to create something using snap-together parts, and this idea somehow emerged. It turned out to be a fantastic fidget toy. When it comes to fidgeting, I prefer keeping the chain as a line instead of linking it into a circle. Important Note: For those who keep the chain as a line, I have included a little end support because the open link on one end tends to get damaged. I experimented with the teeth design on the pin part. At this size, each part measures 2.54 cm, and the teeth work perfectly. None of my chains have come apart, even after extensive fidgeting. When I scaled up the design two times, however, the teeth were too rigid, and some broke off when assembling it. So, if you plan to scale this up, you may want to adjust the teeth design and tolerances. Pro Tip: If you print a set to give away, don't assemble it for them. Let them do it themselves! Print Settings: Supports: Yes Infill: 100% Notes: The small annular rings on the pin are angled so that they don't need support. Make sure supports only go inside the link with two holes and the bridge. If you get support in the small groove of the pin, it can be challenging but not impossible to remove.
