Festool Systainer Stack Closure

I have seen other models that are not close enough to the Festool molded parts. This part breaks ALL THE TIME in normal use from stress. So I worked to save myself purchasing from Festool spare parts. This works 99% like the OEM part. Fit of rotating post seems to vary by materials. PLA works well, ABS-GF was closer color match but a little stiff to rotate.
