Flying Smile Mug

This is a concept I made years ago. Thanks to the 3D printing technology, I made it come true. The main purpose of this design is to bring smiles to your daily life and make happiness with you always. It has 2 versions, 1 is just a mug, you can print it with food-safe filaments; 2 is stainless steel mug sleeve, recommended to print it with soft material such as TPU or TPE, the inside stainless steel mug could be bought at Amazon.com, search"304 350ml". Actually, the stainless steel mug I'm using is not from Amazon, although it's 12OZ(350ml), I'm not sure whether the size is exactly the same as Amazon's. Anyhow, if you like it, just have a try. All the 2 models can be printed without support. See my other designs at  https://www.myminifactory.com/search/?query=Frank+cheung and https://www.thingiverse.com/wuguigui/designs Enjoy!
