Niwood is a 3-in-1 electric precision sander that breaks through the limits of single-tool processing for model makers, bringing linear reciprocating, orbit cross, and rotary modes into one device. Linear reciprocating mode follows a model’s structure and texture, removing excess resin and support marks along a parting line while preserving engraved lines and sharp fabric folds that a rotary head would smudge. Orbit cross mode eliminates one-directional scratches and circular marks, polishing compound surfaces like figure cheeks and clothing folds to a ready-to-assemble finish in a single pass without swapping grits. Rotary mode handles thick sprues, stubborn residual resin, and large printed supports in seconds— far faster than manual filing. A side wheel with precise damping lets you dial speed with a single finger, from low speeds for delicate edges to high speeds for heavy flash, and quick-release grinding heads and clamps cover large-area leveling, fine tips for hard-to-reach corners, and dedicated cutting and polishing.
