Just a simple scale that can be imported to verify model sizes during slicing. Primarily intended for use with D&D style miniatures. Base is a simple 25mm square 2mm thick with scale marks for 28, 32, 45, & 75mm. Measurement starts from the top surface of the base to the top surface of the scale you want. Just import the model with whatever model you are scaling, set them side by side and manipulate the scale of your model till it matches the scale you are looking for. It should be printable as well, but I haven't tried it and don't really intend to. Edit: added 24 & 21mm marks for vehicle sizing. 24 should be average mid-sized suv, 21 would be a car, both these are based off of 1:64 scale, so paired with a 28mm character.
