DIY Street-Grip GoPro Hero 9-10-11-12 with Battery

Hi Makers and Photographers!

I've designed a modular "Street-Grip" system for the GoPro Hero series, perfect for street photography, vlogging, and everyday shooting.

The main problem I wanted to solve was poor ergonomics and short battery life. This grip feels great in the hand and adds critical functionality.

Key Features:

• Modular Design: The main cage and the handgrip print separately and connect securely with a custom-designed mount.
• Integrated Battery Storage: The handgrip is hollow and perfectly sized to securely store one spare GoPro battery. A friction-fit cap keeps it safe.
• Ergonomic Grip: Makes handheld shooting much more stable and comfortable.
• Wrist Strap Loop: Includes a small hole for attaching your favorite wrist strap for extra security.

Compatibility:

• ✅ Tested & Confirmed: Fits GoPro Hero 9, Hero 10, Hero 11, and Hero 12.
• ❓ Not Yet Tested: I have not been able to test this on a Hero 13. If you do, please let me know the result in the comments!

Seeking Your Feedback!

This is a prototype that I am testing before considering a commercial version. I'm sharing it with the community to get your valuable feedback.

Please download, print it, and share your experience!

• How does it feel?

Your feedback is greatly appreciated. Happy shooting!

(Print Settings Recommendation)

• Prints in 3 parts: Cage, Grip, and Cap.
• Designed for easy printing. Recommend printing the cage on its back.
• Material: PLA+ or PETG for durability.
• Supports: Minimal supports may be needed depending on your printer's bridging capabilities.
