Dual Protractor (also can be used as a Square, Edge Line Marker, and Centre Finder) This is an extremely simple yet handy marking tool. Its main purpose is to find or transfer angle markings…. but it can do a whole bunch more! See Images below and in listing photos for it's other tool uses.Tool 2: Centre FinderTool 3: Edge Line MarkerTool 4: Square Line Marker As per my other tool models, this design had to be:fully 3D printableversatile and with decent resolution & accuracy for the degree scales.Robust! and so able to stand to a workshop environmentThis model is the result & I am really pleased with how it turned out. It feels super sturdy and has a very satisfying sliding action. Zero support required, and as mentioned, no need for metal fasteners as the securing bolt & slide nut are printed too. For better accuracy, I have opted for minimal clearances on the sliding guide rails, so once assembled it may be necessary to rotate the plates around their travel range to bed them in.
