Chemex Cone 1-3

I like my Chemex coffee maker a lot but sometimes I struggle with the filters not really sticking well to the glass. So I decided to make a cone to make this a little easier.Edit on 2024-12-31: Added the possibility to “store” the glass cap with can and cone. So you have everything together :-). The four “fingerprints” were added as they make grabbing the cone more easy. And the texture … I cannot say if it enhances the thing but I thought it was a good idea.
