This is a small pot designed to house a 2.5-inch planter, without removing the plant from the container it comes in. These are the small sized pots containing cacti and succulents at Home Depot. There is a drain hole at the bottom.
The model supports multi-material printing, with the coil part being a different color. The 'combined' version is for printing with a single color.
