For an historical rebuild, I needed a ruler that represent the unit of length used from 1668 to 1799 in France.
Pied (Foot) du Roi/Pied Parisien = 324.84mm
Pouce (Inch) = 1/12 Pied = 27.06mm
Ligne (Line) = 1/12 Pouce = 2.25mm
I used prusa to cut in half the model, I can remake the STL if needed
The author marked this model as their own original creation.
