The actuation plate of the Marker Ski binding on my favourite Völkl Skis broke away - without that plate it is not possible to open the binding with the ski pole anymore. Marker service does not help, they are only referring to the dealer the skis were bought at.
I decided to design a plate - print was done in PETG, 100% filled, using supports and placing the plate upside down on the print bed (not the best solution for quality of the top surface though).

This fits to the special Marker Binding of 'Völkl VWerks Code' Skis - but probably also other Marker bindings are using the same lever design for the acutation plate, have a look at the photos to compare to your version.
