The original insert in the top of these pods are cupped allowing the seal on the Keurig coffee maker to distort causing it to leak water. This splashes down behind the cup causing a mess. I modelled a new insert right in the Prussia Slicer. So if you need to resize the outer diameter for a better press fit you should be able to easily. This happens if you printer isn't calibrated the same as mine. I printed mine in Petg and it solved the leaking problem.
The author marked this model as their own original creation.
