A three-dimensional (3D) drawing device having a housing configured for manipulation by a user's hand and to accept a feed stock that is, in certain embodiments, a strand of thermoplastic. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand of thermoplastic feed stock such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object.

A three-dimensional (3D) drawing pen can include a housing that has a port that permits insertion of a strand of material into the housing, an actuator for controlling a movement of the strand, and a nozzle assembly configured to permit the strand to be extruded out of the 3D drawing pen in a form that retains its shape against gravity in free space to draw a 3D object.

The method for dispensing of a liquid, viscous, pasty, powdery, or gaseous product by means of a dispensing device (100) adapted to being held and manipulated by a single hand of the user U comprises: Taking a dispensing device (100); Selecting a connection tip from a tip assortment A through G, each of them having a previously defined function; Securing the tip chosen from the tip assortment A through G inside the dispensing device (100); Selecting a mode among the different modes of the control program; Positioning the dispensing device (100) in the work zone; Activating a control button (400); Releasing the control button (400); Removing the selected tip from the dispensing device (100);

A three-dimensional (3D) drawing pen can include a housing that has a port that permits insertion of a strand of material into the housing, an actuator for controlling a movement of the strand, and a nozzle assembly configured to permit the strand to be extruded out of the 3D drawing pen in a form that retains its shape against gravity in free space to draw a 3D object.

A power tool system includes a removable battery pack a first tool and a second tool. The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.

An apparatus including a three-dimensional (3D) drawing pen can permit a user to draw in free space to form a 3D object. The 3D drawing pen can include a housing, an actuator, and a nozzle assembly. The housing is configured to receive material therein and fit in a user's hand. The actuator is coupled to the housing and is configured to control a movement of the material. The nozzle assembly is configured to permit the material to be extruded to permit the user to form the three-dimensional object.

A glue gun, comprising: a housing for storing strands including thermoplastic plastic, a heating device, an outlet nozzle for discharging heated strands from the glue gun, an extrusion unit for shaping extruded strand, a conveying device for conveying strands to the heating device and through the outlet nozzle. Embodiments of the disclosure make it possible to store glue in the glue gun even in large amounts and to join the parts to each other with a strand of fiber-reinforced plastic with adhesive bonds in such a way that the adhesive bonds can withstand even large forces. Various glue guns of the disclosure include a pultrusion unit for consolidating fibers and plastic.

A waxing apparatus including a dispenser having a compartment for holding wax and a tip having an aperture for dispensing wax on a user skin, the tip including a gradually decreasing cross section in the direction towards the aperture; and a heating element mounted over the compartment and over the tip and configured such that temperature inside the tip is higher than temperature inside the compartment.

An adapter is configured to be mounted onto or otherwise coupled to a hot-melt adhesive dispenser. The adapter may include a body defining at least a first inlet channel, a second inlet channel, and a feed channel. The first inlet channel is configured to receive a first adhesive. The second inlet channel is configured to receive a second adhesive. The feed channel is configured to direct at least one of the first adhesive or the second adhesive to the hot-melt adhesive dispenser.
