Flowerpot Spacer Ring for Improved Drainage – Multiple Sizes

I created these Plant Pot Spacer Rings to tackle a common problem: stagnant moisture building up at the roots of plants in flower pots. After noticing some of my favourite houseplants struggling with soggy soil, I designed these rings to lift the pot just a few millimetres above the trivet. This simple tweak allows more air to flow underneath, helping excess water drain away more easily and keeping roots healthier.

To make life easier, I’ve included several diameters and heights so you can pick the best fit for your pots and trivets. Whether you have a small herb pot or a large decorative planter, there’s probably a ring size here that’ll work for you.

How to Print the Spacer Rings

You’ll find a PrusaSlicer project file in the downloads, which should give you a good starting point for your print settings. Here’s a quick overview:

Feel free to experiment—this print is very forgiving!

Dimensions & File Naming

All files are named following this format:

LR2249-H<height>-D<diameter>.3mf

• D = Diameter: The number after the “D” is the outer diameter in millimetres.
• H = Height: The number after the “H” is the ring’s height in millimetres.

Pick the size that matches your pot and trivet setup.

How to Use

Just pop the ring under your flower pot with the fins facing down. That’s all there is to it—let the airflow and gravity do their work!
