Servo Hub Arm

A few years ago I was building some projects for halloween and needed a specific servo arm length to produce a bigger up/down effect. I went back to the site this year and the part was gone. With the original part in hand I created a newer version. I made it for this specific coupling connector:https://www.amazon.com/dp/B09WJQLMWT?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Coupling connector fits M3 machine screws (3mm). PLA or PETG should be sufficient here.
