Simple hockey puck rebounder legs.
Use a chunk of plywood, 4 eight millimeter or 5/16, or 1/4 bolts and a bungee cord.
Adjust the tension as needed with a screw under the board or wrap it around a leg like I did.
Make sure you leave an overhang on the board so that the puck can't pop up when it rebounds.
