Lens hoods are essential for photographers. They reduce glare, protect lenses, and improve contrast, especially when shooting outdoors. But if you’re using Canon’s RF-mount cameras, official lens hoods can be costly or difficult to find. Enter the 3D printed lens hood for RF mount, a custom, budget-friendly solution that lets you design the perfect accessory for your setup. In this guide, we’ll walk through how to 3D print a lens hood that’s functional, stylish, and tailored to your specific RF lens model.
Why Print a Lens Hood for RF Mount Lenses?
Canon’s RF series lenses are modern, sharp, and well-built, but accessories like lens hoods often come at a premium. 3D printing gives you a better option:
- Custom sizing: Match your exact lens diameter and focal length
- Lightweight design: Reduces weight while maintaining effectiveness
- Affordable: Save money with less than $2 worth of filament
- Easy replacement: Reprint if lost or damaged
- Creative design: Add vents, logos, or extended shapes for personal style
Whether you’re a hobbyist or a professional, it’s a fast upgrade for your gear.
What Type of Lens Hood Should You Use?
Different focal lengths benefit from different hood shapes:
- Petal/Flower-style: Best for wide-angle lenses to prevent vignetting
- Cylindrical: Ideal for standard and telephoto lenses
- Tapered designs: Great for mid-range zooms
Ensure your hood matches the lens’s field of view to avoid interfering with the image.
Filament Options for Lens Hoods
For outdoor durability and visual appeal, consider:
- PLA+: Easy to print, strong enough for general use
- PETG: Better for high-temperature conditions (sunlight exposure)
- ABS: Good heat resistance, but needs enclosure
- Carbon Fibre PLA: For a sleek, matte look and higher rigidity
Matte black finishes are recommended to prevent internal reflections.
Print Settings and Tips
- Layer height: 0.2 mm for strength and speed balance
- Infill: 15–25% is usually enough
- Walls: 3–4 for durability
- Supports: Use for bayonet clips or overhangs
- Bed adhesion: Brim suggested for round base models
- Orientation: Print vertically to maintain shape precision
You can fine-tune the inner ring tolerance (+0.2mm) for a snug but non-scratching fit.
How to Fit a Lens Hood to an RF Mount
Most RF lenses use a bayonet-style mount for the hood. You’ll need:
- Accurate measurements of the lens ring (callipers help)
- A locking bayonet ring modelled to match Canon’s dimensions
- Snap-fit or twist-lock mechanism printed into the hood design
- An optional felt lining inside the ring for a secure, scratch-free grip
Look up your lens model (e.g., RF 50mm f/1.8 or RF 24-105mm) for exact specs.
Post-Processing for Better Performance
- Paint the interior matte black to absorb light
- Add a textured finish or print in matte filament to prevent reflections
- Use a heat gun for slight adjustments (carefully)
- Label or engrave the lens name for the organisation
Some photographers even add lens cap slots or tether loops to the design.
Use Cases in the Field
- Outdoor portraiture: Reduce flare in backlit scenes
- Event photography: Lens protection in crowded areas
- Landscape shooting: Improve contrast in bright skies
- Urban photography: Avoid smudges or bumps during travel
You can also design collapsible or nesting versions for travel gear.

FAQs:
1. Will a 3d-printed hood affect image quality?
Yes, in a good way! It reduces glare, boosts contrast, and protects the lens from flare.
2. Is PLA durable enough for outdoor use?
Yes, for short exposures. PETG or Carbon PLA is better for environments with a lot of sunlight.
3. How do I ensure the hood fits properly?
Measure your lens precisely and test with a small sample ring before printing the whole hood.
4. Can I design a reversible or collapsible hood?
Yes, with clever layering or snap-fit parts, reversible designs are possible.
5. Are there free models available?
Yes, search Printables or Thingiverse by your lens model. Always verify dimensions.
Conclusion:
The 3D printed lens hood for RF mount lenses is one of the most valuable and affordable upgrades any Canon mirrorless shooter can make. With just a few grams of filament, you can improve image quality, protect your lens, and customise your gear with your personal touch.
It’s a bright print for serious shooters.
