Ricoh GR III & GR IV Ultimate Street Grip

The Story: Form Follows Function (and tons Hours of Testing)

The Ricoh GR series is a masterpiece of pocket photography, but let’s be honest: when you’re out on the streets for hours, shooting one-handed, the original grip can feel a bit flat. You need confidence, a secure hold, and zero fatigue.

I’m a designer and a maker, but above all, I love functional design. That’s why I didn’t just want to create another 3D-printable handle. I wanted to build the perfect extension of the Ricoh chassis.

This project took months of development, countless design iterations, and field testing to get exactly what i was looking for.

🔍 The Iterative Process

• The Perfect Curve: I went through multiple physical prototypes, tweaking the finger groove and the palm swell by fractions of a millimeter. The goal? Maximum comfort without sacrificing the legendary pocketability of the GR.
• Obsessive Tolerances: The bottom plate has been refined over and over to ensure a perfect alignment with the camera body, eliminating any wobble, twisting or gap.
• Real-World Abuse: This grip wasn’t just tested on a desk. It went with me everywhere, facing hours of real-world street photography to test ergonomics, sweat-resistance, and structural strength under use.

🌟 Features 

• Flawless Access: The battery door and SD card slot open perfectly. You never have to take the grip off to swap batteries on the fly.
• Ergonomics First: The deeper, sculpted front ridge gives your fingers a natural resting place, dramatically reducing hand strain.

🛠️ Filaments & Print Settings 

To match the premium feel of a Ricoh GR, the material choice is crucial.

• My Personal Recommendation: PETG-GF (Glass Fiber). Testing showed it’s the absolute best option. The glass fiber reinforcement adds structural rigidity and gives the grip a gorgeous matte, textured finish that naturally mimics high-end camera gear while providing an anti-slip texture. PETG or ASA are also excellent for outdoor durability.
• Infill: 25% (Gyroid for maximum internal strength).
• Walls/Perimeters: 4-6 walls. This is vital to give structural integrity around the mounting screw.
• Layer Height: 0.2mm 
• Supports: Yes, only under the screw's seat.
