JK3D.us Sapphire Motorsports Camera Lens Protector V3.5

Description

A camera lens is the one part of your action or dash cam that can’t be replaced without replacing the whole camera. The JK3D.us Lens Protector puts a genuine sapphire crystal in front of it — the same material used on Rolex watch faces — so the grit, sand, and road debris that would wreck your lens hits the sapphire instead. It’s the highest-end protection you can buy for the camera capturing your best rides.

Update — May 2026: the V3 design has been made more compact and is now the V3.5. Newly negotiated sapphire pricing also let me lower the price.

Why it’s worth it

• Genuine sapphire crystal — the hardest optical crystal you can buy, used on Rolex and other high-end watches for a reason. It’s virtually impossible to scratch, so road grit and sand won’t mar it and it’s safe to wipe clean. JK3D.us is the only company using this material for a camera lens protector. Cheap plastic protectors aren’t replaceable and look hazed and scratched within a year.
• Waterproof, dustproof design — built from the ground up to seal around the lens, so driving rain and dust storms don’t leave debris or fog between the protector and your camera. You get a clean, clear image every time. Most cheaper protectors can’t do this.
• Superior case materials — carbon-fiber Nylon-12 with high-temperature, very soft TPU seals printed right into the case. Proven around the world since 2020, it’s shrugged off big hits and won’t bend or crack even in the coldest weather.

Key features

• Body — carbon-fiber Nylon-12: high durability, high strength, and chemical resistance.
• Front seal — a super-soft TPU seal printed into the structure holds the sapphire crystal and gives a first layer of dust and water resistance.
• Rear seal — a camera-specific TPU liner for a secure, snug fit. (INNOVV N2/N3 2K and CHIGEE cameras also get a carbon-fiber nylon sleeve that attaches to the camera.)
• Endurance-tested sealing — cameras were left submerged for 12–24 hours, far exceeding IPX67 and similar standards.

INNOVV cameras

The N2 2K is unique among the INNOVV cameras — it uses a carbon-fiber shim like the CHIGEE AIO cameras do. Order the correct option for your front camera (the rear on the K5/K6 matches the N1/N2 series, K7, K3, K2, and C5).

• 1 × JK3D.us Motorsports Lens Protector housing
• 1 × sapphire lens
• 1 × TPU seal/insert matched to your camera model
• 1 × 3 mm screw and Nyloc nut

N2 / N3 2K kits also include (assembled like the CHIGEE kit below):

• 1 × INNOVV N2/N3 2K carbon-fiber nylon shim
• 1 × 0.8 oz tube of E6000 cement

CHIGEE AIO-5 / AIO-6 / XR-2

The AIO-5, AIO-6, and XR-2 have a conical front, so this kit includes a carbon-fiber nylon adapter that bonds on with the included E6000 cement. The adapter doesn’t affect how the camera works, but it may not come off easily once bonded, so only fit it if you plan to run the protector. Because of the extra adapter and glue, the CHIGEE kit costs a little more.

• 1 × JK3D.us Motorsports Lens Protector housing
• 1 × CHIGEE carbon-fiber nylon shim
• 1 × 0.8 oz tube of E6000 cement
• 1 × sapphire lens
• 1 × CHIGEE-specific TPU seal
• 1 × 3 mm screw and Nyloc nut

Buying from a one-person shop

I design, engineer, print, pack, and ship every part myself — and I’m the person who answers your email. This protector has been refined over six years and multiple generations of real-world use.

What this product is — and isn’t. It’s designed to add real protection against sand, dust, dirt, and small debris, and to keep water and fog out. It is not guaranteed to protect your camera against every impact — large road debris, gravel, or rocks can still damage the camera (and the protector itself). There’s no implied or guaranteed protection beyond what’s described here.
