Display Stand Half Circles

I kept seeing this style shelf on amazon for displays and figured why not make it?

Its a 3 tier half circle display shelf that comes fully apart. Everything is push fit and snaps together.

Total print is 9h13min and requires 274 g of filament with print profile.

The Small top layer is 150mm tall, 130mm wide and 65mm deep.

The Medium layer is 115mm tall, 250mm wide and the shelf is 60mm deep.

The Large layer is two sections with a connecting middle. 80mm tall, 205mm&215mm 410mm total wide, and the shelf is 80mm deep.

The large 1 will need supports under the connector.

All the shelves are 5mm thick and the posts are 10mm in diameter.
