GoPro with 5.4mm lens ring

thingiverse

Just upgraded my lens to a 5.4mm lens from RageCam? Try this handy ring to help you focus on the fly. I'm offering two sizes: a compact one that fits perfectly inside a GoPro lens filter attachment, and a larger one for when you're shooting naked. The small ring is ideal for indoor shots, while the large one allows you to adjust your focus more precisely. **Instructions** I printed these instructions with 100% infill so they'll last. When you're done calibrating, first find something in the distance and set your lens's autofocus. Next, twist the ring all the way until there's no gap between it and the housing of the lens. To focus on a subject up close, simply loosen the ring by turning it to the left – it's that simple!
