The Double Shear Stepper Mounts allow both ends of the stepper shaft to be supported, limiting shaft flex even more.
The kit includes 30mm spacers, and m3x45mm bolts which extend from the top of the Double Shear Stepper Mounts, through the spacers and nema17 mounts, and into the stepper itself. Note: Longer bolts maybe be needed with use of a Halo.
