Here's our take on the Igloo IceCube Mini Cooler. The Top has a functioning flip up lid with storage below it. You'll need to print at .100 layer height or better for the built in hinge system to print right. There's ~.2 gap between the lid hinges and channel inside. The handle is a tension fit and needs to be worked into the cooler by rotating back and forth a bit after putting into the sides of the cooler
Top is printed with no supports on our Wanhao D6 and Ultimaker 2+. If you can't bridge very well and need supports the lid might not open right... You printer needs to be dialed in for this print to work successfully with the small tolerances.
