Storage box for trumpet mouthpieces/Caja de almacenamiento para boquillas de trompeta

I've made this box for my wife. This box make mouthpiece storing more safe and allows get them all together to jam/recording.

Print should be fine with almost any plastic but I've printed it with PETG cause it more tought and not so brittle like PLA. No supports are required.

You can use M2.5/M3(they both working fine) screw(and nut) for attaching cover to box.
