QuackyBrush 3D is a freestyle 3D modeler and painter. Tap to place primitives — sphere, ellipsoid, cylinder, capsule, cone, frustum, torus, box. Move, resize, rotate, mirror, group, and carve them into anything you can picture. When the shape is right, bake to fuse the primitives into a single smooth model. Then paint directly on the surface. Save as a Creation. Place it in a Scene with a movable light and other models. Render the scene to your camera roll. Built for everyone - ideal for 7+ (kids who play Minecraft/Roblox or other 3D games performed well in UX testing). The interface respects your time. Drag-first input on top of an SDF + smooth-min CSG engine. Premium creative ownership - buy once, no subscription. What you can make. Stuffed animals, cute characters, low-poly game assets, 3D-print-ready props, game mascots, geometric sculpture, snowmen, ducks, chess pieces, mushrooms, robots. The primitive set composes into more than its parts. Negative-space carving. Switch any primitive to Carve mode and it becomes a subtractive ghost - eye sockets, mouth slots, embossed details, cavities. Smooth-min CSG fillets the boundary so carves feel hand-shaped, not Boolean-clean. Groups + pre-bake. Build a head, group its parts, pre-bake the group into a single fused unit. Drag the head as one piece while you keep adding to the body. Mirror. X, Y, or Z. Place one ear, get the other automatically. Place one eye, get the second symmetric. Free trackball rotate. Drag in any direction - the model rotates around the axis perpendicular to your finger. Need axis-locked rotation? Switch to X / Y / Z sub-tools. Orthographic toggle: Faux-orthographic camera for design-grade views.
