"Magic Locker" emergency key safe

thingiverse

The "Security Safe" is commonly used in modern chastity devices, including affordable metal ones found on platforms like Aliexpress and high-end models such as the Holy Trainer device. These safes usually come with two keys. The concept behind this key safe is that you can keep a spare key for emergency use while your partner has access to check if it's been used. Simply insert the extra key and secure it through the hole using one of the plastic locks, or opt for a combination or timer lock instead. I've made available an OpenSCAD file allowing you to customize the text as needed.
