Measuring cup for small epoxy resin quantities

The measuring cups are intended for small quantities of Eroxyd resin and hardener. These are difficult to weigh on the kitchen scale. The color change orange/grey and grey/black corresponds to a volume ratio of 45:100 for hardener/resin. The vessels have a volume of 1.14 and 2.56 cm3 respectively. The volume ratios can be adjusted in the Prusa Slicer via the color change, as can the size of the vessels.
