Olight Perun 3 GoPro-Style Mount Adapter

Olight Perun 3 GoPro Mount Adapter

A 3D-printable adapter for mounting the full-size Olight Perun 3 right-angle headlamp to standard GoPro-style mounts.

Compatibility

Designed and tested for the full-size Olight Perun 3.

Approximate flashlight dimensions:

• Body diameter: 26.6 mm

• Head diameter: 28 mm

• Length: 117 mm

• Weight with battery: approximately 150 g

Not compatible with the Perun 3 Mini or Perun 2 Mini.

Recommended print settings

• Material: PETG or ASA

• Nozzle: 0.4 mm

• Layer height: 0.20 mm

• Walls: 5–6

• Top and bottom layers: 5+

• Infill: 40–60%

• Supports: as required by orientation

ASA is recommended for prolonged outdoor, vehicle, marine, or high-temperature use. PLA is suitable only for test fitting or light indoor use.

Print orientation and layer adhesion are particularly important around the GoPro mounting tabs.

Hardware

• 1 × standard GoPro-style M5 thumb screw

• 1 × compatible M5 nut, where required

• Optional thin rubber or TPU strip for additional grip

• Optional safety tether for mobile or outdoor use

Installation

1. Inspect the print for cracks or poor layer adhesion.

2. Insert the Perun 3 into the holder.

3. Attach the adapter to a compatible GoPro mount.

4. Tighten the screw without crushing the printed tabs.

5. Check the fit and shake-test the assembly before use.

A thin rubber or TPU strip can be added if the flashlight fit is slightly loose. Lightly sand the internal contact surfaces if the fit is too tight.

Safety

This is a 3D-printed, non-certified accessory. Its strength depends on the material, print orientation, layer adhesion, hardware, and operating temperature.

Use a secondary tether where failure could cause injury, damage, or loss. Do not use it as certified PPE, climbing, diving, firearm, or other life-safety equipment.
