According to examples, a machine may include a base housing and a handle assembly mounted to the base housing and extending at an angle from the base housing along a handle plane. The handle assembly may include a mating component having a plurality of slots arranged at multiple angular positions along a slot plane, the slot plane being parallel to the handle plane. The mating assembly may also include a handle segment rotatably mounted to the mating component, the handle segment housing a locking member, in which the handle segment is rotatable along the slot plane relative to the base housing and the locking member is removably insertable into a first slot of the plurality of slots when the handle segment is in a first angular position and is removably inserted into a second slot of the plurality of slots when the handle segment is in a second angular position.
