My 3D printer pays for itself fixing broken household parts, not printing toys

A 3D printer's real value isn't in decorative prints but in replacing broken household parts — clips, brackets, spacers, adapters — that manufacturers don't sell separately or charge too much for. The author argues that printing replacement parts saves money and reduces waste, but cautions that savings aren't automatic: failed prints cost filament and time, and printed plastic shouldn't be used for load-bearing, heat-exposed, or safety-critical applications. The true benefit is control and speed — the ability to create a part that fits your exact situation rather than waiting for an order or discarding an otherwise functional item.
