Dial indicator clamp for Duet3D smart effector 8mm

thingiverse

This clamp mounts to the Duet smart effector and lets you use a dial indicator to calibrate your printer. The clamp accepts 8mm shafts and requires 3 M3 screws to mount to the smart effector. Naturally, the inner diameter of the holder won't fix the shaft exactly, so use a 8mm drill to widen the hole a bit.
