6 And 10 mm Cove And Roundover Sanding Block
A 70 mm-long sanding block with four profiled faces for 6 mm and 10 mm radii. The convex faces sand router-cut coves, and the concave faces sand roundovers, so you get an even radius instead of flat spots from your fingers. Wrap a strip of sandpaper over the matching face. It prints standing upright, so every profile is a vertical wall, and the hollow core keeps it light and cheap.
Square Edge Sanding Block With Fence
A hand sanding block with a built-in 90° fence. The fence rides against the face of a board, shelf or acrylic panel so the edge you sand stays square and doesn't round over. It has a 100 x 52 mm sole for a strip of PSA or taped sandpaper, a 15 mm-tall fence, and a 2 mm relief groove so paper and dust in the corner can't push the fence out of square. It prints upside down, so the sole and fence faces print flat, and the ribbed hollow body keeps it light (about 70 cm³).
