This is a Piggy Bank in the Style of a Coffee Mug. The lids can be screwed on and off easily.
I provide several lids and bases for different purposes:
Bases:
- Mug Base with handle (Mug)
- Mug Base without handle (Tube)
Lids:
- Kaffeekasse with money slot (german)
- Spendenbox with money slot (german)
- Kitty with money slot (engl.)
- Donation with money slot (engl.)
- Tips with money slot (engl.)
- Plain "Crema Edition" with money slot (non-flat lid surface)
- Plain lid with money slot
- Plain lid without money slot (so just a lid)
Just look at the .stl files for the lid that fits your purpose (If Thingiverse rendered them...). If you chose the base without handle and the lid without money slot you get a closed multi purpose storage box.
And of course: This mug was not designed to actually hold liquids. You probably can get it watertight though, by tuning the gcode in your slicer (lots of walls, ironing, .1-layer height, ...) and by chosing TPU or ABS as print material.
