Pegboard Panel & Peg Hook Generator

Pegboard organises tools, craft supplies and desk accessories — and printing your own lets you choose the exact size, hole pitch and hole diameter. The panel tab creates a rectangular panel with a grid of holes (default: 25.4 mm pitch, 6.4 mm holes, 4 mm thick, rounded corners) in any number of columns and rows with an edge margin; the hook tab creates a two-peg hook with a backplate, a horizontal arm and an upward hook, with peg diameter, length, spacing, arm length and rise as parameters.

Both are solid, manifold meshes with a 3D preview and downloadable as STL or 3MF. Make the pegs about 0.3–0.4 mm smaller than the board's holes, print hooks with the layers perpendicular to the arm's bending direction if you can, and use thick walls: the long arm of a hook acts like a lever.
