ISO viscosity flow cups

I needed a set of visocity meters and found drawings with rough dimensions online for different types. This collection is for ISO 9431 standard cups in dimensions 3, 4, 6 and 8 mm.

The "ISO * mm.stl" files are full cups with correct hole size. The "ISO cup basis.stl" in combination with the "* mm tip.stl" files form a complet set of cup with inserts for reduced filament use.

The four different dimensions cover these ranges of viscosity:
3 mm: 4.6-52 cSt
4 mm: 19-163 cSt
6 mm: 84-823 cS
