Summary

A ring from a "Universal phone case" https://www.thingiverse.com/thing:6432227, for those who don't know how to model in SolidWorks and can't customize this case to fit their phone. For everyone else, I recommend printing a "Universal phone case" - it's more practical.

With this ring, you can hold your phone on your finger, even while wearing a thick winter glove. You can also place it on a table at any angle. This ring is compatible with "Phone hand mount" https://cloud.mail.ru/public/PgJ5/WRxp27o9y and "Boom arm phone holder" https://www.thingiverse.com/thing:7181014.

To assemble you will need nails with a diameter of 1.7 mm. Process it as shown in the photo. The plate should be glued to the phone or case with glue or thick double-sided tape. Material for printing: wheel - TPU 95A, everything else - PETG.
