This generator creates grid organizers which can sit in your vase or pot to stabilize flowers for arrangements.
A flower frog is an insert that sits in the mouth of a vase and holds flower stems upright, so arrangements keep their shape instead of flopping to the sides. Traditional flower frogs are heavy glass domes, metal cages, or spiky kenzan pins. A 3D printed flower frog does the same job with a light grid that rests on the vase rim: the brim keeps it from falling in, the body sits just inside the opening, and each cell holds a few stems exactly where you place them.
This generator designs one to fit your vase. Enter the inside diameter of a round vase (or the width and depth of a rectangular planter), choose a minimum opening size, and the tool packs a hexagon honeycomb — or an optimized rectangular grid — into the space, with a live 3D preview and an editable engineering drawing. The Download STL button exports a watertight, print-ready model in millimeters, already oriented flat-side-down so it prints without supports on any FDM printer.
Printing tips: measure the tightest interior point of the vase mouth (the generator subtracts fit clearance for you), and print in PETG filament — it handles water and sunlight far better than PLA, and translucent PETG nearly disappears in a glass vase. A typical frog uses 20–40 g of filament and prints in a couple of hours.
