3.5mm Audio Keychain
thingiverse
This is a versatile dust-protector for standard 3.5mm audio jacks that can also be used as a handy keychain holder. Crafted with precision using Tinkercad, its diameter measures 3.7mm - although my printer surprisingly printed it at 3.6mm (I need to recalibrate mine). As a result, you may need to adjust the X and Y sizing accordingly.
