12 Must-Have 3D Printed Camera Accessories

Camera accessories are notoriously expensive. A simple lens cap replacement can cost ten dollars, a flash diffuser twenty, and a custom mounting bracket even more. Meanwhile, most of these items are simple shapes made from cheap plastic. This is exactly the kind of problem 3D printing was made to solve.

I started printing camera accessories out of frustration after losing a lens cap on a hike and discovering that the replacement would take two weeks to ship. I printed one that night. Since then, I have printed dozens of camera accessories, and many of them outperform the commercial versions because they are customized for my exact gear.

Here are 12 camera accessories worth printing. Every item links to 3DSearch to help you find the best model.

Lens and Body Protection

1. Lens cap — Replacement lens caps sized for your specific lens diameter. Print a few extras and keep them in your camera bag. The snap-fit designs work just as well as the originals. Search for lens caps on 3DSearch

2. Lens hood — Custom lens hoods designed for specific lenses. Some are petal-shaped for wide angles, others are cylindrical for telephotos. A proper lens hood reduces flare and protects the front element. Search on 3DSearch

3. Body cap — Keeps dust out of your camera body when no lens is attached. Print several in different colors to distinguish between camera bodies if you use multiple systems. Search on 3DSearch

4. Hot shoe cover — A protective cap for the flash hot shoe on top of your camera. Prevents dust and moisture from getting into the contacts. Takes five minutes to print. Search on 3DSearch

Mounting and Support

5. Camera quick-release plate — A plate compatible with Arca-Swiss or other quick-release systems. Print as a backup or for mounting cameras in custom rigs. Use PETG for the strength needed to hold a camera securely. Search on 3DSearch

6. GoPro mount adapter — Converts a GoPro mounting point to accept a standard camera, or vice versa. The GoPro mount ecosystem is everywhere (helmets, chest straps, handlebar mounts), and an adapter lets you use your full camera on those mounts. Search on 3DSearch

7. Follow focus gear ring — A toothed ring that wraps around your lens focus ring and mates with a follow focus system. Essential for videographers who need smooth, repeatable focus pulls. Custom-sized for your exact lens diameter. Search on 3DSearch

Lighting and Diffusion

8. Flash diffuser — A dome or box that softens the light from your camera's flash. The commercial versions are overpriced for what they are. Printed versions work just as well, and you can experiment with different shapes and sizes to control the light quality. Print in white or translucent PLA. Search on 3DSearch

9. Light modifier grid — A honeycomb grid that attaches to a flash or constant light to narrow the beam. Used extensively in portrait and product photography. Search on 3DSearch

Organization and Transport

10. Memory card case — A slim, protective case for SD and microSD cards. Some designs hold four to six cards with individual spring-loaded slots. Toss it in your camera bag and always have backup storage ready. Search on 3DSearch

11. Filter holder — A case or pouch that holds circular filters organized by size. Keeps them from rattling around in your bag and getting scratched. Search on 3DSearch

12. Lens organizer — A shelf insert or bag divider that holds lenses upright and organized. Custom-sized dividers let you maximize the space in your camera bag or on your shelf. Search on 3DSearch

Material and Printing Tips for Camera Accessories

Camera gear is expensive, so the accessories that hold and protect it need to be well-made:

• Material for structural parts (mounts, plates, adapters): Use PETG for its strength and slight flexibility. Overture PETG is my go-to. These parts need to handle the weight of a camera without cracking.
• Material for caps and covers: PLA is fine for lens caps, body caps, and hot shoe covers. Hatchbox PLA in matte black matches most camera equipment.
• Material for diffusers: White PLA or natural (translucent) PLA works well for light diffusion. The layer lines actually help scatter light evenly.
• Tolerances: Camera accessories often require precise fits. Print a test piece first, especially for snap-fit caps and lens-specific items. Adjust your printer's horizontal expansion setting if parts are too tight or loose.
• Layer height: 0.12 mm for items that need to look professional. 0.2 mm for functional items where appearance does not matter.
• Surface finish: Sand and paint accessories that will be visible during shoots. Matte black spray paint gives a professional finish that matches camera gear.

For help with settings, the AI Settings tool on 3DSearch can recommend optimal print parameters for any model based on your specific printer.

Recommended Filaments for Camera Accessories

• Overture PETG — Structural parts, mounts, plates
• eSUN PLA+ White — Flash diffusers and light modifiers
• Overture TPU — Grip wraps and protective bumpers

The Photography Community Loves 3D Printing

The overlap between photography and 3D printing communities is growing fast. Sites like PetaPixel and Digital Photography Review (DPReview) regularly feature DIY camera accessories, and many photographers share their designs on Printables and Thingiverse.

When searching for camera-specific models, include your camera model and lens specification in the search. For example, "Canon RF 50mm lens hood" or "Sony A7IV battery grip" will return much more relevant results than generic searches.

3DSearch searches across all major 3D model platforms simultaneously, so you see every available design for your specific gear in one place. It has saved me from the frustration of checking four different sites only to find the best version on the last one.
