Ninja Slushi Easy Pour

New to 3D printing and loving it!  This is my first attempt at using cad software so please be gentle :) We recently purchased a Ninja Slushi, instantly I thought it should have come with a funnel of some sort because it is very easy to miss the inlet, my daughter was constantly missing and making a mess! Because of this I designed and printing the Ninja Slushi Easy Pour, She has been using this now for one week without any spills!Make sure seams are on the back or it will add the seams to
