Migiris vegetable grater plug

I made this plug for old Migiris vegetable grater. My parents have same grater, but lost its plug.

I used PET-G filament.

Resolution - 0.2, but to save some time i think it can be printed at 0.3 layer height.
I used 7 walls and 10 top and bottom layers, 30% of infill to make it heavier.
No supports are needed.
Print it upside down.
