Please note that the .ztl file contains 2 subtools , the signet and the emblem . The ring is full inside to those who want to leave it that way , or sculpt more on it . The emblem is a bas-relief that can be used for other purposes , medal , pendant , etc ... Wireframes for the Zbrush file are the last 4 images .
Both obj and stl files have been decimated then exported . The ring is emptied inside for weight purposes .
