Ear & nose Ring Clasp (piercing free)

thingiverse

WARNING! (Sand down sharp edges of the clasp and be careful when putting it on and taking it off!) If it feels too tight, reprint to a larger size to fit, which will increase the mouth opening of this ring. This is meant as a design in progress. Use your own common sense judgment about its use. The ring wire itself is 2mm thick. The diameter of the ring is 20mm. I made the clasp part small to minimize its appearance and to look more like a real pierced ear ring on an ear. And put the bumps in an attempt to give it the ability to hold the weight of ear ring charms. I test printed with ABS, and it seems to be fairly durable, but found the edges are sharp and can draw blood. I filed down to round out the edges and had less trouble. I may make a few different sizes to accommodate more range of earlobe thicknesses. I am also exploring rounding out the edges in the file itself and increasing the size of clasp pads for a more comfortable fit. I welcome your comments. I designed this to use on piercing-free ears for jewelry. This is an ear nose ring clasp (20mm diameter) for ears/noses that do not have a piercing. Be careful to file or sand down sharp edges before putting it on an ear or other body parts. I will be making other models of ear ring clasps. This clasp can be used in conjunction with my ear ring charms. This clasp can also be used as a nose ring for those without a piercing in the nose. Please send me your comments and suggestions. UPDATE: I have added accessory links to attach to the main ring and the attached charms. It is 9mm diameter to the outside edge, the wire is 1mm thick, and has an opening to allow for linking up links together as well. Print as many links as you like. The file is a one-link file. Safety issues: I have been researching what I can find out about the use of PLA or ABS on the skin (as in the form of slaps and nostril area). I could not find much, and what little I did find suggests conflicting information about it. It seems it leans more towards being relatively safe under normal conditions because the melting temperature is over 200 degrees. And body temperatures usually average under 100 degrees max for healthy people. I am not clear if there are any issues below the melting point and at what temperature that would be. So do your own research on what you think about it in terms of safety. And if you are in doubt, you might want to refrain from using it as a clasp on body parts. And if any of you have any more information, please share. I suppose alternatives include having parts printed with known non-toxic materials for piercings? If there are any?
