Time Reminder. At what time?

This is a model that no one but me can use for sure! :-) The reason I made it was because my dishwasher's beeper stopped working and I used it to set the time I had to open the door.
In case someone want's to dare: The model is intentionally very small, only 36 x 20 mm. So for 1:1 scale printing you need a really precise, dimensionally accurate printer. The inner springs, for example, consist of a single wall line and all parts must fit together perfectly. Otherwise it doesn't work.
