KICHLY Cereal box PTFE connector lid (dome-shaped)

In an attempt to build a cereal container drybox with PTFE tube outlet I ordered the cereal boxes linked in many available models just to notice that there seems to be a newer version of them where the hole isn't round but dome shaped. As I couldn't find a fitting model for this cereal box edition, here's my take on it.

 

There are 2 variants, one for M6 and one for M10 PTFE couplers.

 

I printed the M6 version using supports for the hole to make sure the threads are printed good. The M10 version doesn't need any supports.

 

I used these boxes.
