SJ4000 to 37 mm adapter

thingiverse

I replaced a 110° and 3.8 mm distortion-free lens for my SJ4000, but now it's not compatible with the waterproof case! Time has come to install an UV filter. 1. Print both parts. 2. Clear away any fluff carefully. 3. Clean threads thoroughly so that two parts can be screwed smoothly together. 4. Attach a 37 mm UV filter onto the adapter and ensure it screws on smoothly. 5. Clear them again for good measure. 6. Place the base ring onto SJ4000, then screw the adapter securely into place. ### Notes 1. This design will accommodate an SJ4000 with a 3 mm lens protruding from the sheath. 2. This adapter is more stable than many alternatives found online, but it can still come loose if pulled directly. 3. When disassembling the adapter, avoid pulling it directly; instead, try to unscrew it carefully. 4. Disassembling this adapter may damage the SJ4000's panel.
