A power tool comprising:

• an electric motor configured to provide torque to a rotating component in the power tool when activated;
• a printed circuit board including a plurality of heat-generating electrical components;
• a potting boat in which the printed circuit board is received, the potting boat including a base plate and a plurality of sidewalls projecting from the base plate;
• a plurality of cooling fins formed on one of the sidewalls, the cooling fins extending laterally outward from the one of the side walls;
• a recessed portion in a first sidewall of the plurality of sidewalls having a recessed wall portion extending laterally inward from a remaining length of the first sidewall;
• and
• an arm having a first end fixed to the first sidewall and an opposite, second end not connected with the first sidewall, the arm at least partially overlying the recessed wall portion to define a void within which electrical wires connected to the printed circuit board are retained proximate the first sidewall, wherein the electrical wires are routed through the void and over the first sidewall to connect with the printed circuit board.
