I actually figured it out without cutting the tank. I’ll post a pic tomorrow I have this thing where I bounce ideas off someone and in this case I had no one but you guys thanks for the input though I really appreciate it!!From experience...
Use a Dremmel if you have one.
Regardless, cut slow and steady or the plastic just melts.
Take a paper plate.
Cut it in half.
Push the straight portion up under the rim on the inside.
Bend the circle part of the plate to catch the plastic droppings.
