Biohacking is all about tweaking your body, mind, and environment to perform at your best. Whether you’re a quantified self enthusiast, a neurofeedback nerd, or just love self-improvement, 3D printing opens the door to creative gear you won’t find in stores.
These prints are designed to support better focus, healthier routines, smarter tracking, and even enhanced sleep or posture. Some are experimental, others practical—but all are built for performance-minded makers.
Why 3D Printing Fits Biohacking
The tools in this space tend to be niche, custom-fit, and expensive. With 3D printing, you can:
- Build personalized tools around your body and environment,
- Prototype wearables, mounts, or accessories quickly,
- And test unconventional ideas that match your optimization goals.
Perfect for tinkerers, quantified selfers, ADHD tool collectors, or wellness engineers.
