BCR Lock
thingiverse
This thing was made with Tinkercad. Edit it online at https://www.tinkercad.com/things/c9S9m2Zt43U. The purpose of this object, minus the padlock and Ring, is to lock a Ball Closure Ring (Piercing jewelry) shut using a padlock. The dimensions I modeled this on were a 22mm by 3.2mm (8g) BCR, which would need to be re-scaled for different sized jewlery, and a generic small padlock that was sitting on my desk. I'm saving up for a 3D printer, so I won't get to see how it looks in real life yet, but I'm pretty sure the scale is good. Also, the padlock and BCR are just there for scale and demonstration purposes and would be deleted before printing. (Note: It's irresponsible to try locking your piercings. The only reason I'm interested in this is that I'm a bit of an oddball.)
