How are teams mounting drivetrain encoders on WCD?

[Lil' Lavery]

I don't have any pictures unfortunately, but a couple of 1712s students designed a novel mount for the Versa block system. They 3D printed a piece that interfaced with the contour of the Versa block above the 2x1 channel (including the existing mounting holes) and stick out just beyond the end of our drive axle. There was an adjustable encoder mount that was then slid into that overhung lever, allowing a structural element to hold the encoder that could also slide with the Versa block as the block moved to tension chain.
