Abstract: A 3D printer configured to print a 3D part includes an ejector having a nozzle that is configured to eject drops of a build material. The 3D printer also includes a build plate positioned below the nozzle. The drops land and solidify on the build plate to form at least a portion of the 3D part. The 3D printer also includes a first heater positioned under or within the build plate. The first heater is configured to heat the build plate and the 3D part thereon. The 3D printer also includes a second heater positioned laterally-offset from the build plate. The second heater is configured to heat a volume of air between the nozzle and an upper surface of the 3D part. The 3D printer also includes an enclosure. The nozzle, the build plate, the first heater, and the second heater are positioned at least partially within the enclosure.

Abstract: A collapsible air filter assembly for a heating and ventilation air conditioner (HVAC) system includes a filter element, and a frame supporting the filter element. The frame includes at least two edges each including a respective spring element configured to be moveable between an open state and a bent state. A compressible air filter assembly for an (HVAC) system includes a filter medium having rounded pleats configured to collapse and rebound in a controlled and repeatable manner between a compressed state and an original uncompressed state. A soft-wrapped filter assembly includes a frame in a box configuration. The frame includes rigid edges and openings to permit airflow. A filter element is encased by the frame. Flexible edge covers mounted on respective edges of the frame to provide an air seal in an HVAC system.

Abstract: An apparatus for a wrist-worn device includes a frame and a screen fixed to the frame. The frame is configured to be removably secured to the wrist-worn device so that the screen is positioned in adjacent, overlying relationship with a face of the wrist-worn device. The screen is configured to perform one or more of the following: magnify the face of the wrist-worn device, protect the face of the wrist-worn device, provide an anti-glare surface for the face of the wrist-worn device, and provide a privacy screen for the face of the wrist-worn device.

Abstract: Stackable infusion filtration and storage systems are described herein. Components of the systems may include a first container, a second container, and a cooperating third container. The stackable systems may further include a sleeve component and one or more lids. The stackable systems can concurrently capture liquid as the liquid separates from an infused butter mixture and solidify butter in separate cooperating stackable containers. Methods of use are also described.
