I designed this holder to accomodate #2 coffee filters for pour over, 51mm for my espresso and 58mm for aeropress. It can either be wall mounted (screws or adhesive) or set on a shelf.
The filter slots are 2mm larger than what they are designed to hold, so this could be used for slightly larger sizes, or you could upscale slightly for larger filters.
The author marked this model as their own original creation.
