Jingle Bell Lock v2

This is an overhaul of the jingle bell lock. It's round now! Additionally, in OpenSCAD you can change settings to make the model better for FDM or for resin printing, and you can easily add some extra space around the lock slot.

Use this lock for fursuits, petplay, shibari—whatever strikes your fancy. The locking module is a (fairly) commonly available "stealth lock" popularized by chastity cages like the Holy Trainer. It can be found on eBay, AliExpress, and sometimes Amazon by searching "stealth lock" or "chastity stealth lock". I think the original lock design is the "mortise lock" or "keyhole blocker" (Model ME) manufactured by Burg-Wächter. This is the only "professional" use I have seen for this lock module.
