Cairn Caliper

Hi fellow 3d printer people, As I've mentioned before I am a Multi Skilled Mechanic / Subsea Engineer when I'm not designing stuff for you to print, In that environment it pays to have a readily available method of checking sizes of small fittings, bolts etc. A small 6" rule is my usual pocket carry but the last job I was on I printed a few different styles of pocket callipers after seeing someone at work with one. They bought theirs online some cheap nasty mass produced in
