Pebble Earbud Case

A pebble-shaped TWS case with two earbuds

Category: Product DesignLevel: Intermediate

0 views

A wireless earbud case shaped like a pebble: the base and lid are two separate SubD objects so the parting line reads clearly. The hinge, USB-C port and status LED sit on the Detail layer. Each of the two earbuds is built from an ellipsoid body, a stem made with Pipe, a silicone ear tip made with Revolve and a sensor grill. Every object carries a PBR material: glossy white plastic, silicone, chrome and a blue LED.
