3"/75mm Self-watering planter insert (square)

Sub-irrigated (self-watering) planter insert compatible with my 75mm square planter pot designs.   There are two versions of this insert Fill hole cutout with an optional floating water level indicator is included. The stick is a tight fit and you'll likely need to sand the sides on both ends to fit. No fill hole (mostly for use with multi-insert planter design)   On the bottom of the insert there are three built-in break-away support panels. You should be able to snap them off easily. The squares on the bottom have a single-layer of filament. It's optional whether you remove these strands. The purpose is to provide air flow and better drainage to prevent excess water in the soil. The filament strands should not affect functionality.     Compatible planters: Rectangular box planter (holds 3 inserts) - Optional Mother's Day decoration Modern Minimalist Square Planter   - I'm learning and having fun with this. Feedback letting me know how your print went would be greatly appreciated. If you're feeling generous and like what you see, Buy Me a Coffee or just Send me a tip.
