Cục hít giảm chấn cửa (Door soft closer)

TPU door soft closer.

My interior doors are mostly sprung closed, as each room has individual heating control, and my kids like leaving them open.

On some doors the spring closes the door with a bit of a bang, no problem in the day but a pain at night.

As such, and after a few design trials, this working version has proven itself and was printed with 95A TPU.
