Focus handle

thingiverse

This lever arm serves as an upgrade for the Neewer follow focus unit, empowering users to push or pull their way to precise focus control. The design seamlessly integrates with the 1/2" drive by slipping over the knob. To achieve a perfect fit, I printed this part on a medium setting with a 0.25mm layer height and performed a minor trim/shave afterwards. The resulting snug/friction fit works remarkably well in practice.
