Stocking test tube Waterproof Survivalist

Hi !

So here i'm explaining this tool.

Here is my new idea that was very problematic for me, i wanted some sort of test tube that can be carried easily in my bag or pocket for multiples tasks like collecting plants seeds, little leaf and flower but for other tasks.
Extremly usefull because it can be sealed and waterproof. It can containt things dry without problem.

Concerning the fillet there will be no probleme even if you have unprecise 3D printer or a poor quality of printing ;)

For technical information here we go:
Internal diameter 16mm OR 18mm diam/45 mm deep

It can be resised without affecting problem, the fillet is made of my work
I use for all my conseption a standart fillet, 3.33 mm for the pas, and triangle shape with 3mm base 2.5 to 3mm eigh
The two parts together is 51mm heigh. Far the smallest tube. Heigh are told in the picture.

I use it for :
-Seeds
-Pellet
-Steel balls/Ball bearing
-Matches
-Powder
-Spices :Salt/Pepper/mint/ect
-Ammo
-Fishing tool
-Rope and other
-Electronical components
-Magnets
-Food
-Money
-Toothbrush
-Small tools
-Screw/bolts
-Earbuds / earprotecions
-Etc etc (comment your idea :D )

I also add two tiny grip on the lid for people who want to add this to wear on a belt .

Inner friction and pression of the fillet make it waterproof without O ring ;)
