What I canged compared to the original case from CNC Kitchen:

I reduced the free space above the tips in the lid of the case and added a Tip Adapter holder on the side of the lid.

The Tip Adapter is attached to the case by his M5 thread for the tips. For this you will need a “M5 Short” (~M5x6x7) threaded insert that you can already insert with your new adapter ;-) 

As it is not that easy to insert the threaded insert through the upper hole without melting this, I made two versions. On with a blind hole for the experienced guys and a more simple one with a through hole that you can insert from the lower end.

You still need to print the basic case from the original version, as I did not do any changes on that. There a two versions available from Stefan, which you can choose from.
