Ready to level up your desk setup? The Spiral Ball Fidget is a satisfying, interlocking kinetic toy that’s as much an art piece as it is a stress reliever. I designed this specifically to fix the "fitment headache" common with other spiral models, giving you a print that actually stays together and isn't too loose or too tight.
What’s New in This Version?
I’ve moved past the "one size fits all" approach. This model features:
Choose Your Size:
40mm: Pocket-sized. Perfect for EDC (Every Day Carry) and stealth fidgeting.
60mm: The standard. Fits most hands comfortably.
80mm: The "Goldilocks" size. Great for two-handed use and looks awesome as a display piece.
100mm: The Desktop Giant. A serious conversation starter and a fun challenge for your printer.
No Support Needed: The geometry is optimized to print clean without wasting filament on supports.
Quick Print Guide
Filament: Silk PLA is the goat for this model—it makes the spiral shadows pop.
Layer Height: Stick to 0.2mm or lower. The curves need that extra detail to feel smooth in your hand.
Walls: Run at 2-3 perimeters. The higher the perimeter count, more durable the "links" are.
Infill:Â The to get a different sound from your fidget, you can change the infill density. When the infill is very low (0-5%), the fidget will sound high pitched and loud. If the infill is denser, the fidget will have a more mellow tone. (there is less difference in tone with the smaller sizes)
Pro Tip: If your first layer is a bit squished (elephant’s foot), turn up the "Elephants Foot Compensation" in your slicer by 0.5-1mm (the links will stick pretty badly if there is an elephants foot).
Show it off! There are a million color combos possible here—print the spirals in alternating colors or go for a full rainbow. If you print one, post a Make! I’m still tweaking the files based on your feedback, so let me know how the fit feels on your printer. (Likes are appreciated and sometimes rewarded)
Update 13/4/26:
I have begun experimenting with a different link shape. This shape is more space efficient so now I can get more links into a fidget ball. So far, I have only tested a 50mm fidget with 18 links. I have also been working on an Extra Large, 150mm size fidget.
Update 27/4/26
I finished testing the Extra Large, 150mm size fidget. The 50mm fidget with 18 links is still in development. The new link shape is more space efficient so I can fit more links into a smaller shape. I am working on different sizes with the updated links.
