(mini) Bar Straightener by Giova

thingiverse

I designed this gadget to tighten loose Z screws on my 3D printer. It's a crude solution, but it gets the job done. The accuracy is within 0.5 millimeters, so feel free to scale down the smaller components if you encounter any issues. The hardware required includes M4 screws longer than 70 millimeters and corresponding nuts. When printing, set the infill percentage to 25% and avoid using supports for this particular project.
