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.

Systems and methods for a container for decreasing the thawing time for a liquid, gel or other fluid material is described herein. The systems can include a container with a body. The body can include a cavity with a dispensing nozzle and a plunger disposed within the cavity. The body can further include one or more channels separate from the cavity. The channel(s) increases the rate of heat transfer associated with the container and, thus, increases the cooling or heating rate of the material within the container.

An application device for paste-like and/or flowable material, including a housing with a feed region for material and at least one discharge region for material. At least one mixing region is formed between the feed region for material and the discharge region for material and the at least one mixing region is designed as at least one mixing device.

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. The strand can be moved through the housing toward 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 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 three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.

An improved cartridge structure that both heats the materials contained therein and provides for enhanced structure such that the bypass leaking of the low viscosity heated components is avoided. The cartridge is preferably formed from a rigid material such as reinforced fiberglass tubing. The wall of the cartridge is then wrapped in a flexible heating element or has a heating element cast directly in the wall thereof. The heating elements preferably heat the interior contents and epoxy cartridges to between 150 degrees and 180 degrees Fahrenheit. The wall structure may be of single wall construction with the heaters embedded therein or of a double wall construction such that the heaters are contained between an inner and outer wall. Further the wall construction is preferably formed to withstand the pressures applied when spray applying the epoxy contained therein to prevent the tube wall deformation and resulting blow by leakage.

Aspects herein relate to an applicator wand that is configured to melt a solid marking material and apply the melted marking material onto a receiving medium. Aspects of the applicator wand include a heating and melting element enclosed within an external casing, a receiving compartment configured to receive one or more solid marking materials, and an applicator tip for applying the melted marking material onto a receiving medium to create a design, drawing, picture, sketch, and the like on the receiving medium.
