Ikea metod cabinets doors are intended to be mounted using hinges screwed inside the cabinet. I needed the doors also mounted outside. That requires something that simulates 18mm cabinet wall so I created this model.

There are 5 holes that you can use to mount it to the cabinet - I used just 3 and it works well - just make sure to use the one furthest from the door. Mount using screws with countersink.
