HO Scale Ruler

thingiverse

This ruler is for approximate scaling of .stl files in your slicer software. Simply import the ruler into your slicing software and place your .stl file to be resized next to it and adjust the scale. When done simply delete the ruler before slicing. It is graded in 1:87 scale (HO Scale) in increments of 1 scale foot, with timing marks every 5 feet. I use this to get approximate sizing, it is not intended to attain exact measurements!
