Eccentric Nut Wrench Protractor

This tool is built to make adjusting those tricky eccentric nuts a whole lot easier. It works by using the angle of your wrench to give you more control over the adjustment. I've included the wrench model in the files, in case you're handy with a metal cutter. But no worries if not, you can just redesign the bracket to fit your existing wrench.

I whipped this up in Fusion 360 for a Longer Lk4, but it should work on most similar printers. The design already has a built-in tolerance of 0.1mm for a snug fit.

Powerpoint and Inkscape was used to create protractor marks and numbers.

Here's a pro tip: If your nut doesn't have any markings, try painting a stripe or dot on the tighter side of the metal. That way, you'll have better control as you tighten it up.
