About this model

Inch and metric versions of a two piece printable micrometer. The Inch micrometer has a travel length of 2.5 inches and the metric has a travel length of 30 mm.

I have printed both versions and the inch version is generally accurate with in +-3 thousandths. The metric version can be really accurate (+-40 microns). I strongly recommend printing the calibratable versions of the base piece. This version is designed so that you can sand down the clamping point until you get the accurate measurements. If you use the standard base piece you may end up with measurements that are offset by 15 thousandths or so. EDIT (1/12/1…
