Can measure from 3mm to about 80mm.

I print with PLA, 33% infill, Brim and full support.

I've not been able to print the Gauge or Fasteners with threads that actually work, so the Gauge1/Gauge2 and Fastener models comes without threads, you need a 10mm metric tap and die (For M10 nut/bolts) and thread them yourself.

1. Print Base.stl,Fastener.stl,and either Gauge1.stl or Gauge2.stl
2. Use a 10mm tap/die to create threads on the gauge and fastener.
3. Print e.g. http://www.vendian.org/mncharity/dir3/paper_rulers/UnstableURL/rules_cm_narrow_20cm.pdf on a printable sticker.
4. Cut and align the printed ruler on the Base using calipers
