Dial Caliper remix

Needed a caliper for measuring things larger than the generic vernier caliper can measure. So after quick search in Thingiverse I came across lots of options, but the Dial Caliper by LoboCNC seemed the best option. But since the available size was rather small for my needs, I took the liberty of recreating the original model in OpenSCAD and in larger scale.

The available model is 200mm tall, and should be able to measure objects that are up to 170mm, although the accuracy will probably suffer
