Easy print for beginners, at least if you are familar with supports.
The item on the photo is printed with a 120% resizing to have it bigger. Resizing works in a large range, so maybe you replace your kitchens wastebin :-D
Original size (12cm diameter) requires 110 g filament, 120% enlarged size requires 190g.
Regarding supports:
Glue ring to lower half and glue button to ring. No screws needed. Maybe its useful to glue the upper halft to the ring, too.
Mounting the flap to the upper half is obvious, just bend the upper half a bit.
The author marked this model as their own original creation.
