Transparent film ruler for models that
measures extremely narrow widths and circles
It is a tool to measure the width of the groove by printing the line width of the actual size on transparent material.
When you want to re-engrave the groove applied to the plastic model with a tool,
but you do not know which width of the tool will fit, apply it to the place you want to measure as shown in the figure, and check the size of
the matching width. You can upgrade from actually applying tools to the grooves
to more accurate measurements.
Small diameter size can also be measured
The size of the circle can also be measured. When looking for a
size circular masking seal (sold separately) that fits, you can easily measure it with a micro gauge.
