Hộp đựng CMF Buds Pro 2

The case is made of PLA, but it can easily be reproduced using other materials, although I recommend using rigid materials since the body and lid snap together. 

To open the lid, a slight force on the corners is required.

Additionally, there is a small ring for attaching a keychain, a hole to view the LED indicator, and a USB port for charging the case's battery where the earbuds are stored. 

I would like to specify that the design of the USB port is based on the data cable provided with the purchase of the earbuds, or any other cable with similar dimensions. 

Furthermore, there is a hole at the top of the case that allows you to use the aluminum ring without any issues.
