Insta360 One R 4K adapter to 58mm filter

thingiverse

Printing with PLA is possible and yields a tight fit for 58mm filters, requiring minimal sanding for easy insertion. Once in place, these filters don't come out easily. Consider printing one filter adapter per 58mm lens to ensure seamless compatibility. For 4k lenses, the adapter fits tightly as well, necessitating some light sanding to facilitate smooth installation. With the right fit, no additional reinforcement is necessary for secure holding. Printing in PLA was successful; experimenting with TPU may also produce viable results. I'll update this information once I've tested it with TPU materials. Note that support structures are required during printing.
