Tired of soil on the floor and your cat using the plants as a litter box? This cover sits on top of the pot and keeps paws out of the soil, while water still runs straight through the honeycomb holes.

FEATURES

• Fits around plants that are already potted – the cover is split into pieces that lock together with dovetail joints. No repotting needed.

• Water straight through – no need to remove the cover when watering.

• Stays in place – a ring goes down into the pot and keeps the cover centered.

• 27 ready-made sizes for round and square pots, each with a small and a large plant hole.

• No supports needed.

HOW TO PICK THE RIGHT FILE

1. Measure the INSIDE of your pot at the very top (diameter for round pots, width for square pots).

2. Find the file whose "fits" range your measurement falls in. Example: your pot measures 143 mm → use "fits-140-149mm".

3. Choose small hole (young plants, thin stems) or large hole (thick stems, bushy plants).

The file names tell you everything:

PRINT SETTINGS

• Layer height: 0.2 mm

• Walls: 3, infill: 15–20 %

• Supports: none – print flat side down, as the file is oriented

• Material: PETG or ASA for outdoor use, PLA is fine indoors

ASSEMBLY

1. Turn the pieces over so the ring points down.

2. Place them around the plant and press the dovetail joints together from above.

3. Lower the cover onto the pot – the ring goes inside, the edge rests on the rim.

If the joints are too tight, lightly sand them or print with a little less first-layer squish. Too loose? A drop of glue fixes it.
