Taking inspiration from the button I originally designed, I designed this button-rotating portable pill box. This thing is no more than 8 centimeters in size and is suitable for stuffing into a bag. Since it uses a printed scroll spring, it is It is normal for the buttons to get tired after a long time. The buttons that were originally designed and printed have been placed for about 3 months and are still able to operate, so they can still maintain a good validity period. Of course, if the springs become tired Okay, just print another one.

------------------------

I strongly recommend that this design must be printed with a layer height of less than 0.2. I have tried 0.3~0.42 heights but they always get stuck.
