Hirschmann Pipetus top button replacement

Replacement top button for the Hirschmann Pipetus line of pipettes.

Needs to be printed in a soft/flexible material (92A or softer) at 0.15mm layer height.

After printing, gently separate the two halves of the pipette using a prying tool (0.5mm of gap is enough), then slide one edge of the bottom face between the gap and twist-in-place.
