Cheap Driver Replacement Handle

thingiverse

This handle replacement is found in budget driver kits like Harbor Freight or Walcrap for around $3. Its round shaft has been crimped for torque and features a hollow structure to minimize material usage. Print it at 70% scale with settings including a 25.4 STL, 70% Infil, 0.2 Layer Height, and 220C temperature for strong bonding. Be prepared for a tight fit during installation; use sacrificial bits to protect the parts from damage.
