i needed a new door/latch for my old caravan . (Hobby prestige)
So i quickly drew one up that fits over the original frame.
the new frame is shrewd in place with 4 small screws and glued with some "Sikaflex/tec7"
the door is then shrewd and hold in place with 2 hex m5 bolts, might need threading into frame.
the door latches closed so i recommend to use pet-g or similar
one door has power marking other is blank. it has air venting/gap on the side and under, not water tight.
