This is a printable hinge replacement for the Roidmi Eva Vacuum water tanks. Since both water and waste tanks use the same design this fits both. In my case one of the hinges broke off and the top half no longer holds. The replacements requires some cutting and sanding around the water tank hinge to make it fit. Instructions: Print in at least PETG or stronger filament. Minimal support is required for the screw hole part since it is floating. Once printed move the hinge around to release it if its stuck. Adjust X-Y hole compensation in slicer to allow easier printing of the hinge (a setting between 0.1-0.2mm should be sufficient) For preparing the tank instruction file is added.
