Introducing a new and innovative planter that can be easily inserted into the slots of a rotating postcard rack. This planter is perfect for those who are short on space or want to add some greenery to their home or office in a unique way.

The planter is designed to fit into any standard-sized slot on a rotating postcard rack, and it is made of durable and lightweight material, making it easy to move around and reposition. The planter also features a drainage hole to ensure that excess water can escape, preventing overwatering and root rot.

With this planter, you can add a touch of nature to your postcard rack, turning it into a mini garden that can brighten up any space. Whether you use it to grow herbs, succulents, or flowers, this planter is sure to be a conversation starter and a beautiful addition to your decor.

Note: It's recommended that you use PETG filament if you intend to use this for outdoor use. And, it's recommended to use a higher infill percentage and thicker walls to improve the strength of the print. This will ensure that your parts are less likely to crack or break under stress.

Give it a try and see how it transforms your postcard rack into a miniature garden oasis!
