Groovy Filter Holder for 3M strips

thingiverse

I love the original design, but unfortunately, 3M strips just don't bond well with the grooves. Combine that with the fact that the strip hangs over my coffee maker and steams straight up, moisture quickly seeps into the gap between the 3M strips and the grooves. As a result, everything came crashing down during my first pot of coffee. To fix this, I simply added two flat bars to the back of the original design, which allows me to use full-sized 3M strips for a solid stick. Keep in mind that I'm a complete novice at this kind of thing, so it's not exactly a work of art, but with filters in place, you'll barely notice those weird bars on the backside.
