Portable Coffee Maker

Morning in the woods by the lake.
Slowly opening eyes and taking first steps out of tent.
Nature around you is already in action.
You would be to, but you're missing something.
Yes, it is that morning cup of coffee and it would be there with you if you could only pack your coffee maker.

Well here is the solution to this and many more similar situations.
3D printed coffee maker, actually filter holder for coffee that fits on any kind of cup.
It is so portable because it can be disassembled in two parts so it can fit around other things in luggage.

Step 1: Technical Stuff

In .zip file you have .stl file for making this one part. You need to make two same parts to be useful. I hope it doesn't need much preparation for printing because I haven't tested it due to the lack of 3D printer/maker.

Makers dimensions when assembled are 120x120x90mm (approx. 4.72x4.72x3.54in) and it can fit in cylinder of that size, variations in size may occur, but those variations shouldn't exceed +-10mm(0.39in) witch won't make difference in making coffee.

It uses #4 coffee filters

Step 2: How to Use It

When you made all parts, connect two parts and you are ready for brewing!
Place maker on top of cup.
Fold filter and put it in maker.
Put the ground coffee in filter.
Poor boiling water on the coffee and the holy drink will poor in the cup.

Step 3: Summary

After spending time on my instructable I want to thank you for patience.
I hope this is the thing that you have been searching for to print.
I would be very happy if some one makes this coffee maker and shares photos of it.
And please comment in a name of improving design.
