Custom thickeners for M4 rivnuts in centre console

As per usual practise I have fabricated numerous thickeners to provide more of a surface for M4 rivnets to set into (helped with JB-Weld), all from 1mm 6061-T6. The need for this in many of these skins is enhanced as these are fabricated from 0.4mm sheet. This is still within Gesipa rivnut grip range specification (0.25-3mm) but I reckon a slightly thicker layer is perhaps better to reduce the chance of spin-out.
