Insert cho Honeycomb Wall dùng M3 Threaded Brass Insert

I remixed the original insert-empty by @RostaP. The intent was to have a support for the honeycomb wall in which I can insert a threaded brass insert instead of an insert that needs a nut. What I done:

1. First I made the insert full
2. On the inner surface of the insert I made a recess where to sit the threaded brass insert
3. Finally I added a pass-through hole along the entire length of the body so you can use a screw of any length you need.

Edit: This model is for 3mm. X 5.7 threaded insert.
