3 flap dog door

16 7/8 by 10 1/8 dog door three flap replacement. use 1/8 by 3 foot rod from lowes and use soldering iron to stake in. i used 30mmx3mm magnets as my dog door has steal on the bottom and uses 2 doors so i alternated the magnet holes so they dont stick together. i printed on ender 3 in abs standing on edge at angle with supports. flaps infill at 10% and the top bar at 70%. little bit of sanding to make sure it runs smooth and good to go.
