Moccamaster Cup-One Melitta Filter Folder easy hinge

The Melitta No 4 or Melitta 102 filters need to be aligned at the red line in the picture. The No2 filters can be aligned at the provided lip on the top. 

Just print it as you like, i added enough tolerances to print on most settings (i hope).

I printed with .16 layer hight

3 walls 

15% infill

5 top Layers

I found that the hinge was pretty hard to print, so i added a new hinge design, which is easier to print.
Also i made the folding pieces a bit thinner, so that the filter can go out of the top, if you have a non matching curve like the melitta 102 filters.

This still isn't perfect, but gets the job done.
