喇叭帽子

thingiverse

This is a Bluetooth hat made with laser cutting technology and a black cloth module. The design took me a long time to come up with! However, I later found out that this style looks a bit like Shrek's head, so it's often called the Shrek Hat. This is the main feature of this hat. It can be worn on the head and play your favorite songs via Bluetooth or listen to your favorite radio station.
