Abstract: A three-dimensional printed swab may include a shaft defining a longitudinal axis of the swab, and a tip portion integrally formed with the shaft. The tip portion may include a body extending outward from the shaft and positioned coaxially with the longitudinal axis, and a plurality of protrusions each extending outward from the body and transverse to the longitudinal axis. Alternatively, the tip portion may include a body extending outward from the shaft and positioned coaxially with the longitudinal axis, and a plurality of recesses each defined in the body and extending inward toward the longitudinal axis. As another alternative, the tip portion may include a body extending outward from the shaft and positioned coaxially with the longitudinal axis, and a series of annular ribs each extending outward from the body and positioned coaxially with the longitudinal axis.

Abstract: An apparatus for feeding an electronic component to an insertion device using a carrier tape according to the present invention includes a hub having first and second lateral sides and a peripheral surface extending between the lateral sides. The apparatus also includes a tape receiving slot extending into the hub. The slot includes a first laterally extending portion having a first height and a second laterally extending portion having a second height. The height of the second laterally extending portion is smaller than that of the first laterally extending portion for aiding in the proper orientation of the carrier tape within the slot so the electronic components can be properly delivered to the insertion device. The height of the second portion is also smaller than the height of the component receiving compartments. The reel allows the tape to be wound in only one direction so it is not unreeled backwards and the components are not applied to an electronic circuit board in a reverse or wrong manner.
