I share this model to make some delicious onigiri.
It is made up of 3 parts, for deep cleaning (with cold water).
You can use it as printed or covered with plastic wrap and tape on the outside to fix everything.
Personally I use it no covered.
To prevent the rice from sticking to the surface, I recommend running water with your fingers through the printed parts, at each onigiri.
