Pants button

The button of my pants snapped off. No problem. I have a 3d printer. Some modelling, 3d printing and melted two pieces together and its fixed. Now some off you will think its not gonna last long and break soon. Actually it happened year ago and its fine. I have worn them many times during the year and washed with washing machine. And it's printed with PLA. You can use PETG or ABS, they should be much durable.
