This is a heart-shaped lock holder/sleeve/shell for a small MASTER 131D lock.
The lock should be superglued (or using another adhesive) to adhere the lock to the shell. Reccomend adding glue to the bottom or side of the locks. Filler adhesives such as silicon or clay could probably work too.
This model was printed vertically using normal PLA on a Prusa i3 MK3S+ using mostly default values. Supports suggested and ~10-40% Gyroid infill depending on how strong you'd want it to be.
