I printed couple of custom arms with great results. Thank you so much for sharing the openScan source.

Can i know the horn gear spline data please?
Is it a for 25 Teeth servo? and how much is the diameter?

Hello, will these work with a 9 gram micro servo?

I'd love to see a version for smaller servos (3/16" hub - is that a 2F?).
I've tried scaling the whole thing down but that makes the arm very flimsy.

This library is outstanding! Thank you very much for providing this! I was just about to start writing my own when I found this.

I followed your link to https://www.servocity.com/html/futaba_servo_splines.html and found lots of interesting information, but no actual dimensions for the splines. In particular I'm looking for the dimensions for an A1 HiTec servo. https://www.servocity.com/html/hitec_servo_splines.html

ServoCity has some nice images; I'll attempt to work from one of those, but an actual value would be perfect!

Thanks again for the great library!

Your welcome !

Thank you very much!
