Guessing you ended up with a bunch of cone filters on accident?
It's drip coffee not rocket science, see if you can bend/fold the cone filter to hold coffee in the basket and go from there.
Alternatively you can cut the cone filter in half and layer the two halves in the basket to hold the coffee.
I've been down bad on coffee enough that I've straight up used a cheese cloth to filter my coffee, where there is a will there is a way...
