This is a sample carrier for 6x3 DSC crucibles (designed for Netzsch Concavus 30/40 microliter, which are 5mm diameter). It requires two 5x2 mm disk magnets. There is some space to put in labels (e.g. sample name and weight). Based on Parametric Hinge by FM.

There are three versions: "Calibration Samples", "Samples" and no text. I rendered the labels separately for multicolor-printing as in the pictures, but it prints just fine in single color.
I also include a Powerpoint & pdf template for the labels (uncheck “fit to page size” when printing).
