Gridfinity bolt measuring tool

A remix of a model by @NoFate301_303075 on Printables, which in itself is based on Boogie's screw measuring tool. NoFate's model was taller than the 3x2 gridfinity system, so it was not possible to put it directly above other gridfinity bins. I remixed this model to crop everything into the 3x2 size, which means losing the 118mm and 120mm length measurements. There are also some minor improvements making the sides and face to make it look better (in my opinion). I also included colour highlights to make it easier to see the measurements. The colour changes are grouped to layers to minimise the amount of switching and wasted filament. All the measurements are embossed so the model still works in single colour.
