Morden Cuckoo Clock

I always wanted to have a cuckoo clock, but the mechanic one is very limited for our days. I did a search and realized that there is no design in the way I like it. Then I did it. Now it is my pleasure to post here for anyone who wants to make it.
This project has small pieces that can be difficult to print. I recommend printing the small pieces alone, in case it fails, you don’t lose the rest of the work.
Everything was printed in ABS with a 0.4 mm nozzle. The small pieces were printed at 0.1 mm layer height, the others at 0.2 mm layer height.
Recommended items at 0.1mm layer height:
1 x bird_suppport.stl
2 x door_join.stl
1 x gear.stl
4 x hinge.stl
2 x pusher.stl
1 x rack.stl
1 x bird_support.stl

Recommended items at 0.2mm layer height
1 x bird.stl
1 x ceiling.stl
1 x door_left.stl
1 x door_right.stl
1 x house.stl
2 x led_cover.stl
1 x rear.stl
