Ninja Foodi Broken Lid Hinge Fix

Abstract

Ninja Foodi Multi-Cooker OL550EU fell from the table and broke the lid where it connects to the hinge and the base. In order to fix that I found place in the lid where I could connect printed part -- lid ribs. Your case might be different, probably won't see it until you disassembly it. 

Fix

1. Disassembly the lid, see great video on YT from MaximGeek:

2. Check if you have ribs intact on the top of the lid -- that will be the contact point where the printable hinge connects with the lid
   

   

1. In order to minimize the heat and hot vapor I've added silicone pad to close the missing part

2. Print the part in PA12 and assembly

3. Drill holes in the ribs, use some bolts to hold it in place -- but do not do it tight:
   

   

4. The current model does not fit perfectly under the top cover. I think it can be optimized, but honestly I didn't have juice left to make it perfect. So I butchered top cover:
   

   

I also removed springs (part of the hinge at the base), I worried they may put additional constant pressure when lid is closed onto those ribs, as it's the only contact and finally break it. The lid holds opened with it, but it does not help you to lift it and the lid is quite heavy - in general no problems. 

Important notes

The temperatures in that part are high from my measurements -- it easily hits 80C. So PLA even PETG is not options there -- tried and failed drastically.

• PLA is good for fitting and quick tests though, but not for cooking. 

• PETG here was better, I even added silicon pad between the part and hot part (there are tiny holes on the mode for fastening) but when it god heat up the hinge got soft and broke. 

• PA12 (Nylon) - the best way to go from what I had. It holds well, cooking at 220-240 C does not make it soft or show any sign of weakness. So highly recommended for that part. Make sure you dry it as required by manufacturer.
