Skele-Spine - Articulated Snap-Flex Fidget (Tight Joints)

**Print-In-Place, No Supports, Articulating Fidget Toy**

Rising from the depths of the bone yard and the shadows of the catacombs, the Skele-Spine springs to life, ready to thrill and send shivers down your spine! This fidget fiend, shaped like a skull atop an articulated backbone, isn’t just a creepy curio—it’s the ultimate tactile treat for hands that crave a bone-bending twist. Perfect for any eerie ensemble, Skele-Spine yearns to rest on your desk or dangle from your fingertips, catching the wandering eyes of all who pass. While others may be haunted by the memories of goblins and witches, the Skele-Spine insists on making a spine-tingling statement all its own this Halloween season.

This articulated fidget toy integrates the Mimetics 3D "Snap-Flex" joint. This allows the Skele-Spine to both move smoothly, mimicking the fluid motion of living creatures, AND stabilize in a firm pose, providing a premium fidgeting experience. Each **SNAP** will resonate as a symphony of satisfaction to your ears, confirming your masterful manipulations.

This Skele-Spine is the fifth creation in a series of Snap-Flex models by Mimetics 3D, and it's available for free for a limited time.

**Tolerance:**
To accommodate different printer settings and filaments, I’m uploading 3 different tolerance levels for the Skele-Spine to ensure that you get the best fitting, most satisfying “SNAP” with each of your prints.

This is the **Loose** tolerance model.  For the other tolerances, please check out the other versions of the model to be uploaded soon.

Please try out each to see what works best for you, and let me know which version you prefer!


Make sure to revisit us frequently for more thrilling Snap-Flex models to come. We're eager to hear your feedback and collaborate on refining this model going forward.

This model is for personal use only. If you're interested in selling physical prints of this model, please subscribe to the Mimetics 3D Commercial Tier on Thangs.

**Print Settings:**
0.2mm Layer Height
3 Wall Loops
3 Top Shell Layers
No Supports, Print-In-Place at 100% scale.  Going any smaller may disable the Snap-Flex joint.

These tolerances are TIGHT and you'll likely have to snap each segment a few times before it's loose enough to snap/unsnap easily. I recommend you use regular PLA or PLA+. ABS might be even better, but I haven't tried it yet.

Silk PLA is a bit softer and may not click as nicely. I'd also be more concerned about silk PLA holding up to the wear and tear.
If you print this in resin, please let me know how it turns out. I imagine you would need a more flexible/less stiff resin for it to work appropriately.

Knurled Nightcrawler

This “Knurled Nightcrawler” is part of a series of three textured articulating snakes.

See here for video: https://youtu.be/8fIhzqsQP_k 

These textured articulating snakes use a unique print-in-place ovoid joint to create realistic snake movement. This joint type is stronger than the interlocking double ring joints used in many articulated designs, so this design is more suitable for use as a fidget or children’s toy.

The snakes are 54sm in length but will print easily on a 200mm x 200mm build plate.

Like a “ball and socket” joint, the oval-shaped ovoid from one segment is held in place by a similarly shaped socket in the neighbouring segment. Varying the relative dimensions of the ovoid and socket allows for precise control of the movement between each segment. In this design, lateral side-to-side movement is maximized, but rotation and up/down movement is slightly restricted. This more accurately mimics the “tone” and movement patterns of a real snake.

You may get some small adhesions between segments. Simply apply a bit of force to move the joint the first time, and it will be fine after that.

These models demonstrate some of the surfacing and texturing capabilities of nTopology.
