Trimmer Head Feeder, Hitachi - CG22EAS (SLP)

This is the Trimmer Head Feeder for a Hitachi - CG22EAS (SLP) week wacker (the part that you tap to feed the string). They only seem to sell the entire head assembly, which costs around $50 or more. The part shown in the photo was made with ABS on a Robo3D printer, and has been used almost 8 hours without problems.
