Can you tell us more about the situation? Can you see the item? Is it lightweight and metal? Paper, thin, and such?
There are ways to make different tools for different situations but knowing what is involved is a first step for making better suggestions.
you can make some pretty good tools reasonably easy but what you are catching is important.
Magnets, sticky tape on a wire, loop of cord through a pvc pipe to rope it, fish hook on a dowel?
Tubing added to a vacuum hose to snag paper or cloth things?
And then how vital it is to recover will help decide how much you want it back! No need to make a $20 tool to get a ball point pen in most cases?
