I don't know for you but I have a Korg TM-60. It is a good tuner / metronome.
But if you have one you have seen that the back stand is especially weak. And if offers only one angle.
I found that a bad idea so I made my own mount for it.
It offers two angles, 30° and 45° and is easy to print and to use. You only need to turn it 90° to choose the angle.
Let it in your bag or on your desk (or both), and the day it's broken, print one again.
For printing, I suggest you to use infill of 30/40% because a part is relatively thin. But you can print it à 0.2mm.
Have a good music.
Bonjour chez vous.
