Assembly Squares: 3D Print Large Clamping Squares for Square Cabinets and Boxes Every Time

Two large orange 3D printed assembly squares braced inside the corners of a wooden cabinet carcass under construction on a workbench, bar clamps

Introduction Glue-ups have a cruel sense of humour: panels that measured perfectly slide out of square the moment the clamps tighten, and by the time the glue grabs, your cabinet is a parallelogram. Drawers stick, doors hang crooked, and every later step inherits the error. Chasing squareness with a tape measure across diagonals works, but … Read more

Solar Post Cap Light Adapters: 3D Print Fittings to Mount Solar Caps on Any Fence Post

A router guided by a fixed pivot, though, cannot wander: the bit travels at … Read more

Shelf Pin Drilling Jig: 3D Print a Cabinet Shelf Jig for Perfectly Even Pin Holes

Inside a warm-toned wooden bookcase cabinet in bright workshop light

Introduction Adjustable shelves are only adjustable if the pin holes line up. Drill one row a few millimetres off from the row opposite it and every shelf rocks, tips, or sits at a visible slant — and a bookcase full of slightly crooked shelves never stops annoying you. The fix is not a steadier hand. … Read more
