Hatch for chickens

thingiverse

This is too complex to assembly. I leave it here in case you want to use it for some other purposes. This is another try to make a hatch for hen-house. Perhaps works for cats too. Modular design (expandable). Threads ISO Metric, M4x0.7 class 6H right handed and M3x0.5. Axle is 3.5Mx100, which fits to 4 mm holes better than 3.9 mm (4Mx100).
