Outdoor spike Free 3D print model

a 100% infill is neccesary. while PLA can be one time use, any polycarbonate or ABS would actually make it so that they can be used multiple times. why go out to buy spikes when you can have them printed, when ground spikes are constantly being replaced? (i know i would immediately misplace them). these also have heft to them, but the tip of the spike must be sanded down to easy penetrate the ground. can be hit safely with a hammer. be safe while using all forms of tools!
