if your door is to low, because you changed your floor use this door lifter. Just place the printed parts in your door hinge and raise it 2, 2.5, 3, 3.5 or 4mm.

I printed several of these and they have been working for over a year without any vissible wear. I printed mine mine with ABS and PLA all with 75% infill. Until now and can´t say if PLA or ABS is more durable.
