The prompt

i need a mechanical vernier caliper for measuring radii - it needs to be very accurate - be bale to measure mm and microns - i would like the appropriate size that i can still use it one handed - i would like to be able to print this as one print-in-plcae print but if not possible multiples peices are okay - take into account printing tolerances within this component - it would be nice for it to have some type of gearing system or an incurament system that clicks each mm or so for accuracy and stability - i would like this to measure internal and external radii of objects - it could also have some type of release mechanism in order to swap out different lengths measurebale for example if i want to measure just small objects i can use the small "ruler" and then for larger objects swapping to a longer "ruler" - make it easy legible and readable even being 3d printed
