I idea is good. I ordered them because I thought they would have a novel way to replace the filter. It comes with a paper filter inserted into a 1mm deep and 19.7mm wide hole. This type of paper filter has to be replaced after every use. First Is not a common size, they are available at 20 mm, but I don't have it. I use 25 and 35 mm. Providing the 20 mm fits well only provides 4 mm of seal.I normally do this by drilling a 12 mm hole on the cap and using a 25 mm filter, this leaves a 6mm seal around the hole. Better the 35mm filter leaves 8mm of glue around the hole. My advice for the developer is just to have a flat hole, no recess on top and allow the liberty of using various size of paper filters available.
