Hario V60 Dual-Size Filter Holder 01&02

I really liked the original design by ‘whoppingporchard’ but I always have filters in both 01 and 02 size, and two seperate holders would seem to take an unecessary amount of space. So I tried to recreate the orginal design but combining the 01 and 02 holder into one. I also felt there should be an opening in the back of each slot for cleanliness.
