A portable power tool includes a housing, a motor enclosed within the housing, an accessory tool holder secured to the output shaft of the motor, and an attachment interface on a nose portion near the accessory tool holder. An attachment is configured to attached and removed from the nose portion of the housing. The attachment includes a housing interface that is configured to interact with the attachment interface to position the attachment at a predetermined position on the nose portion of the housing. The attachment interface and the housing interface are configured to be magnetically attracted to each other with sufficient force to retain the attachment on the nose portion of the housing during normal operating conditions while allowing the attachment to be removed from the nose portion of the housing by hand by the operator.

An improved detector device for locating studs and other objects behind a substrate (such as a wall) uses one or more light emitting diodes (LEDs) in combination with a photochromic compound to mark the locations on the substrate behind which objects are located.

A desktop laser cutter configured to cut a cylindrical workpiece includes a laser, a cutting head that receives an electromagnetic beam from the laser and emits a cutting beam, and a gantry that supports the cutting head relative to a base plate of the laser cutter housing. The gantry can be actuated to move the cutting head within a plane that is parallel to the baseplate. The cutting head emits the cutting beam in a direction parallel to the plane. In use, the cutting head is disposed side-by-side with the workpiece and the cutting beam is applied to a side of the workpiece that faces a sidewall of the laser cutter housing. The workpiece is supported by the gantry to rotate an amount that is a function of movement of the cutting head in a direction parallel to the plane.

A hand-held rotary tool includes a housing that encloses a motor having an output shaft. The tool includes a quick connect adaptor configured to connect an accessory to the output shaft. The adaptor includes a driver that is connected to the output shaft and rotates in concert with the output shaft. An outer surface of the driver has a first flat. The adaptor includes a receiver that includes a connector configured to detachably connect with the housing, and a torque transfer device configured to receive the driver. An inner surface of the torque transfer device includes a second flat that engages with the first flat in such a way that rotation of the driver results in rotation the torque transfer device relative to the connector. The adaptor includes an output device that supports the accessory and that is driven by the torque transfer device to move relative to the connector.

A hand-held rotary cleaning tool includes a housing that encloses an electric motor and a gear set that connects the motor to an output shaft. The rotary cleaning tool includes at least one cleaning accessory that is detachably connected to the output shaft, and a flexible splash guard. The splash guard surrounds the output shaft and cleaning accessory so as to prevent liquid splash during tool use. The splash guard includes a reinforcing ring that is formed of a material that is less flexible than the material used to form the splash guard body. The reinforcing ring prevents the splash guard from excessive deformation, whereby interference of the splash guard with the cleaning accessory or the output shaft is minimized or avoided. The reinforcing ring may also include other features which enhance the cleaning function of the rotary cleaning tool.

A hand-held rotary cleaning tool includes a housing that encloses an electric motor and a gear set that connects the motor to an output shaft. The rotary cleaning tool includes at least one cleaning accessory that is detachably connected to the output shaft, and a flexible splash guard. The splash guard surrounds the output shaft and cleaning accessory so as to prevent liquid splash during tool use. The rotary cleaning tool also includes a reservoir for storing a liquid cleaning solution, and a liquid delivery line that delivers liquid from the reservoir to the space enclosed by the splash guard.

In one embodiment, a laser engraving system includes a laser transmitter and a lens assembly configured to focus a transmitted laser beam onto a workpiece supported by a workpiece support surface. A rail system movably supports a base which in turn supports a mirror and a camera. A controller is operably connected to the camera and is configured to execute program instructions stored in a memory to obtain first image data from the camera indicative of a first location of the laser beam on the mirror when the camera and the mirror are at a first rail system location, obtain second image data from the camera indicative of a second location of the laser beam on the mirror when the camera and the mirror are at a second rail system location, and output a mirror adjustment signal for the mirror based upon the first signal and the second signal.

A 3D printer for synthesizing objects includes: an extruder configured to extrude layers of filament through a nozzle onto a build surface; a build platform; and a build plate that is structured for being removably clamped to the build platform and that includes the build surface, where the build platform includes a base, a heating layer, at least one compressible biasing element arranged between the base and the heating layer, and a clamp, and where the build platform is configured for receiving the build plate into a clamping position in which the clamp is configured to releasably clamp the build plate onto the build platform above the heating layer, causing the at least one compressible biasing element to compress and bias the heating layer upwards towards the clamped biasing plate for even distribution of heat by the heating layer over the planar extension of the build surface.
