This is a design I made that comes with ground stakes for a tent, the hammer for the stakes, and a pry bar that fits the stakes to pull out of the ground.

I print the hammer head and handle separately so that I can add more infill to the hammer head as well as bottom layers.

I printed with 24% infill and that seems to be sturdy enough for these.

Stakes have extra spikes that will fit over the stake holes on a tent for extra hold.
