Ultra Instinct Sonic Figure

This is a stylized “Ultra Instinct” Sonic-inspired figure with a focus on sharp hair, solid proportions, and something that actually prints well without being a nightmare.

I printed this one myself (what you see in the photos), and it came out surprisingly strong even with all the spikes and detail. Supports came off pretty clean overall.

Print Details:

• Height: ~6 inches
• Print Time: ~3 hours
• Filament Used: ~50g PLA
• Printer: Bambu Lab (tested on A1 Mini / P1S)
• Supports: Yes (tree supports recommended)

What to Expect:

• Hair spikes hold up with proper supports
• Structure is solid—doesn’t feel fragile
• You’ll have a little cleanup around support areas (waist, hands mostly)
• Works well with standard PLA and metallic/silk filaments

Included Files:

• STL file
• Print-ready 3MF (same setup used for the print shown)

Made using an AI-assisted workflow and then dialed in for actual printing.

If you print one, I’d love to see how it turns out. Feedback is always welcome—especially if you find ways to make it print even cleaner. I’ll also be refining this over time and dropping updated versions as I go.
