Improved fan for Ferm TDM1026

thingiverse

This fan is specifically designed for use with the Ferm TDM1026 column drilling machine, which boasts a powerful 350W motor. Although it resembles a white label machine, modified slightly, this fan can also be used on other drills. The default fan (visible as black in the image) lacks directional blades, meaning air isn't forced into the motor, causing overheating when used for extended periods of time. This fan, however, forces air directly into the motor, effectively preventing overheating issues. When installing this fan, note that a snug fit onto the motor axle requires some filing to be done on the hub area due to its slightly tight fit.
