Gap measuring tools

Hello !If you like my work, please rate it. I spend a lot of time designing objects. It requires a lot of measuring. Sometimes there are gaps, gaps that are difficult to measure with conventional tools. This is where this type of gap gauge comes in handy. It takes into account the difference between the actual size and the printed size. For example, if a gap fits exactly with a 3.2mm spacer, it is actually 3.4mm wide, but you have to print it at 3.2mm.Anyone who is involved in this kind of design will understand its benefits.It contains spacers from 0.8 - 7 mm, in 0.2mm steps.
