Anet A8 extruder handle

thingiverse

More convenient than pressing a button and less agonizing than its predecessor, I employ an allen screw of sufficient length to retain the spring in place. Two spacers can also be printed for placement under the extruder fan during this process, a feature that might have been included in the original packaging but was not. These spacers are situated between the extruder motor and heat shield, serving to secure both the fan and motor with greater stability.
