The design of the SharkBite Quick Connect removal tool is not particularly ergonomic. It can be very difficult to remove a quick connect when the pipe is deformed or space is tight. I remixed swholmstead's fantastic removal tool by adding/changing the following:

1) Added ergonomic thumb/finger holds
2) Making it less deep so it can fit in tighter spaces (ie between sharkbite and an elbow)
3) Added a thin lip on the inner (top) side so it fits into the sharkbite release better

Modeled in Rhino 7.
