This is a storage model I made for mother's day.
It is quite customizable, depending on what you are looking for and also makes for a great gift.
The design features:
I printed the parts with regular old PLA on an Ender 3 V2 Neo printer with the standard Cura slicer settings and a 0.2 mm nozzle.
Please note, that the indented lid can be screwed in upside down and thus can function as both of the provided lids, though if you aren't intending on printing out the Heart Key, you should probably still pick the non-indented one.
This about sums it up, happy printing!
