Thought someone may find helpful how I managed to repair the screw posts that had stripped threads. It may also help repairing cracked posts.

I took a piece od brass tube with id 1.7 mm and od 2.4 mm, cut four pieces under 10 mm long, cut M2 threads in them, glued them inside the posts. I had to clear the holes a bit with 2.5 mm drill bit before the tubes fit in.

I found the correct diameter brass tube on Aliexpress. I could buy SS M2 screws locally.

All the best,

Nice idea and good photos to help explain.

When sharing something like this, it's always helpful to also share a link to the exact thing to buy. You did supply precise specs. however an exact link, it removes all doubt that it is the exact same item and that it will work.

Thanks for sharing this!
