Waterproof beach storage tube

Hi,

this is a waterproof storage tube for your money or other things,
a nice gadget for beach, camping, prepper, or geocaching.

It is realy waterproof because of the o-ring.
You need a O-ring with a inner diameter of 31mm and thickness of 3,5 maybe a thickness
of 3mm would be easier to open and close the cap but i have dont test it.

!!IMPORTANT!! (fitting information)

I made the design wothout tolerances!
If you print it without scale it down the cap will not fit to the tube!
For the most printers a scale of 0,97 should be ok.
In Repetier Host you can scale induvidually for each axis.

So you should scale:

X : 0,97
Y: 0,97
Z: 1 >Don´t scale the Z axis!

If you scale the Z axis the pitch would be incorrect!

If the cap does not fit, dont worry.
scale the cap bigger or smaller and print only the cap again.
