The invention relates to a device for holding a component. The device comprises a clip, and the clip comprises a head and one or more clip surfaces for contacting the component to be held or an element on which the component is to be held. The clip surface faces the head at a distance therefrom, and a clamping part is provided which supports the head from the head side facing the clip surface or is connected to the head, said clamping part having a contact surface which faces the clip surface. The device further comprises a spring which is arranged so as to pre-tension the contact surface away from the head in the direction of the clip surface.
摘要:
A component is provided that includes at least one passageway. In another aspect, a component, such as a lamp or a vehicular washer jet, is made of layers of material, a light curable material and/or multiple built-up materials. Another aspect uses a three-dimensional printing machine to emit material from an ink jet printing head to build up a component.
