Yazzo Servo Linkage

thingiverse

This item lets you attach an arm to a servo via a 20mm round servo horn. Its 12 mounting holes match the servo horn's, although only four are typically used. The center material has been removed to prevent warping and shorten print time without affecting strength or rigidity. This version accepts a simpler, cheaper bushing instead of a ball bearing. To use it, print as many as needed, insert the horn into the larger receptacle, secure with screws from outside, ensuring the horn opening faces outward. Slip onto servo axle and fasten with provided tiny screw. The lighter weight reduces torque demand on the servo, which is beneficial.
