Hinge Set for German RepRap X400's Housing Lid

This hinge set comprising six things will ease the X400’s maintenance access from top of the machine. From now on the machine’s lid can be easily pulled to open from the front to the back.
The hinge things also have a built-in end-stop which prevents the lid to flip over to the rear side of the printer.
The hinge set is to be installed on the printer without drilling anything or modifying the machine. All components for the lid are simply pushed onto the acrylic glass and on the profile site
