insulated mug (big)

Just something I ran off quick on Tinkercad. I have an old PET insulated mug from the hospital I love and have never found a suitable replacement, so I made this. Good volume the fill is 20% so there's a good amount of air to insulate so you don't get condensation all over your desk from your giant cup of ice water. I do want to run this threw blender sometime and increase the polygon count, smooth it, round the top edges and tweek the handle a bit, but Im new to all this... gimme time.
