Flexible Fish Bone 2
🕑 Added 2025-06-30 15:25:27 +0000 UTCππ
I accidentally came across a pendant in the shape of a fish skeleton with a Cuban chain as its joints.
Inspired, I made a similar version βοΈ for my original design [Flexible Fish Bone].
I also added an elongated version with a moray eel head.
For the ring hole, you can use the eye or the mouth.
The moray's mouth has teeth and is not fully closed.

I also came across a chain called fishbone, where each link has two protrusions resembling bones.
I printed small versions at a 70% scale. Previously, I used to leave gaps of at least 0.3mm, but modern printers can handle much smaller clearances without the parts fusing into a solid block. At a 70% scale, this fish model has gaps just slightly over 0.1mm (comparable to a human hair).
I made a parametric continuous version of this chain for you. By changing one parameter (the number of links), you can adjust the chain's diameter. For example, I have two samples in my hands at 70% and 77%.
To edit the file, you'll need Fusion 360.
Simply open the file Chain+Bone v3.step using this program (hotkey Ctrl+O, then in the dialog window, select "Open from my computer..." in the bottom-left corner and choose the desired file).
Go to "Modify", select "Change Parameters", and adjust the "count" parameter (number of links) to achieve the desired length.
Then save the file (Save As Mash)βyou can set a low quality setting since it won't visually affect the result (the links are quite small anyway), but it will reduce the file size and ease the load on your slicer.
In the slicer itself, you can further scale it down if the default link size seems too large or if the chain doesn't fit on the print bed. However, I wouldn't recommend going below 70%.
You don't necessarily need an AMS to print this chain in two colors like I didβjust swap the filament at the right moment.
Gold and green were two random colors I chose; apparently, I'm still stuck on the "vegetable" theme of flexible keychains, and this chain looks more like something plant-based πΎ rather than bone-like π .
