This part was initially designed for my ‘PluGuard Extensible Collection’ and can of course be used for other purposes, to measure a Gap / Space between 2 parts

Simply slide the gauge between 2 objects, like on the picture between your Desktop and the USB cable (or any other parts) until you feel a resistance, and then read the measure on the increment that felt no resistance (in 10th of mm), i.e. 46 = 4,6mm

The increment is 0.4mm so that you can print it in 0.2mm resolution and have a fair degree of accuracy.

The scale goes from 1.6 to 10 mm to accommodate small gaps between objects; I’ve also split it in 2 shorter models, for thinner and thicker gaps in case the full-length model is too long
