I am trying to couple an HS-65HB mini servo that has a 25 teeth B1 spline to a 1/4" shaft, but I do not find a coupler, does any one have a suggestion? I tried to 3D print the piece but I don’t find tech specs
Hi @hebertodelrio and welcome to the forum!
Your HS-65HB mini servo has 25T B1 spline: https://www.servocity.com/servo-spline-info
I couldn’t find exact coupler for that size, only for bigger ones.
But, maybe you could use something from this: https://www.servocity.com/set-screw-shaft-couplers
Or, you have a caliper, do measurements of both servo spline and 1/4", draw in a CAD software and print on 3D printer!
