Pistol-shaped Drill Bit

Disassembly damaged the charging module's solder joints, rendering it inoperable. Rather than troubleshooting, I'm sharing the STP file; adapt it to your motor as needed.

My previously purchased pistol drill battery from a certain online retailer malfunctioned, preventing charging. Recently, I encountered a model for an aggressive pistol-shaped fan—the design seemed perfect for adaptation!

Materials: a disassembled pistol drill (its screws are reused), a microswitch, and six readily available ST2.5 screws. My pistol drill motor failed, necessitating a spare 18650 battery; a functional drill obviates this need.

The pistol drill's main motor and gearbox are housed within the extended silencer.

Two wires are soldered to the microswitch, which is then installed into the trigger mechanism. The control switch is desoldered and the microswitch is connected, after which the control board is inserted and the reversing switch is positioned for side access.

The charging module is secured to the base, the retaining clips are fastened, and final assembly is completed.
