Folding Pocket Ruler

thingiverse

Create a 12-inch foldable pocket ruler by following these instructions. First, print both parts of the template. Allow them to cool down on a flat surface to prevent warping. Next, assemble the parts by snapping them together. For better visibility, use a sharpie to highlight the numbers and dashes. Note that due to ABS shrinkage during manufacturing, the extended ruler may be slightly shorter, at around 11-and-7/16 inches in length.
